Reaction of methyl bromocycloalkanecarboxylates with zinc and dihydroisoquinoline derivative

The reaction of 5?7-membered methyl 1-bromocycloalkanecarboxylates with zinc and 6,7-dimethoxy-3,4-dihydroisoquinoline leads to 7,8-dimethoxy-5,9b-dihydro-2H,4H-spiro{azeto[2,1-a]isoquinoline-1,1?-cycloalkan}-2-ones. In the case of 1-bromocyclobutanecarboxylate, 9?,10?-dimethoxy-7?,11b?-dihydro-2?H,4?H,6?H-dispiro{cyclobutane-1,1?-pyrido[2,1-a]isoquinoline-3?,1?-cyclobutane}-2?,4?-dione is formed. The structures of the products were confirmed by X-ray diffraction.

Enantioselective template-directed [2+2] photocycloadditions of isoquinolones: Scope, mechanism and synthetic applications

A strategy for the enantioselective [2+2] photocycloaddition of isoquinolones with alkenes is presented, in which the formation of a supramolecular complex between a chiral template and the substrate ensures high enantioface differentiation by shielding one face of the substrate. Fifteen different electron-deficient alkenes and ten different substituted isoquinolones undergo efficient photocycloaddition, yielding the cyclobutane products in excellent yields and with outstanding regio-, diastereo- and enantioselectivities (up to 990 ee). The mechanism of the reaction is investigated by means of triplet sensitization/quenching and radical clock experiments, the results of which are consistent with the involvement of a triplet excited state and a 1,4-biradical intermediate. The variety of functionalized cyclobutanes obtained using this approach can be further increased by straightforward synthetic transformations of the photoadducts, allowing rapid access to libraries of compounds for various applications.

Synthesis of alpha-aminonitriles using aliphatic nitriles, alpha-amino acids, and hexacyanoferrate as universally applicable non-toxic cyanide sources

In cyanation reactions, the cyanide source is often directly added to the reaction mixture, which restricts the choice of conditions. The spatial separation of cyanide release and consumption offers higher flexibility instead. Such a setting was used for the cyanation of iminium ions with a variety of different easy-to-handle HCN sources such as hexacyanoferrate, acetonitrile or alpha-amino acids. The latter substrates were first converted to their corresponding nitriles through oxidative decarboxylation. While glycine directly furnishes HCN in the oxidation step, the aliphatic nitriles derived from alpha-substituted amino acids can be further converted into the corresponding cyanohydrins in an oxidative C-H functionalization. Mn(OAc)2 was found to catalyze the efficient release of HCN from these cyanohydrins or from acetone cyanohydrin under acidic conditions and, in combination with the two previous transformations, permits the use of protein biomass as a non-toxic source of HCN.

Intermolecular Regio- and Stereoselective Hetero-[5+2] Cycloaddition of Oxidopyrylium Ylides and Cyclic Imines

We have developed the first intermolecular hetero-[5+2] cycloaddition reaction between oxidopyrylium ylides and cyclic imines with excellent control of regio- and stereoselectivity. Surprisingly, divergent stereochemistry was observed depending on the substitution pattern of the oxidopyrylium ylide. This new reaction provides quick access to highly substituted nitrogen-containing seven-membered rings?azepanes. Notably, a broad range of oxidopyrylium ylides and cyclic imines participate in this novel hetero-[5+2] cycloaddition reaction and the cycloadducts can be readily transformed into the core skeletons of bioactive natural products. DFT calculations revealed that the cycloaddition proceeds through a stepwise pathway and the imine nitrogen atom serves as the nucleophile to initiate the cycloaddition.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Recommanded Product: 6,7-Dimethoxy-3,4-dihydroisoquinoline, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 3382-18-1, in my other articles.

Linquats: Synthesis, Characterization, and Properties of Linear Extended Diquats

We report an innovative synthetic route to linear extended diquats (linquats). Our approach is short and efficient and features a highly modular reaction sequence based on two-fold quaternization followed by the key intramolecular [2+2+2] alkyne cycloaddition. The physico-chemical properties of four new linquats were characterized by spectroscopic methods, X-ray crystallography, and electrochemistry complemented by information obtained from DFT calculations. Electron deficient N-heteroaromatic cations with linear extended diquat motif with high electron affinities have been recently recognized as attractive n-type semiconductors for chemical and biological sensing. Their advantageous redox properties such as very fast reversible electron transfers make the title compounds interesting for applications.

Synthesis and Crystal Structures of [(Nicotinic Acid)2H] +I-, [(2-Amino-6-methylpyridine)H]+(NO 3)-, and the 1:1 Complex Between 1-Isoquinoline Carboxylic Acid (Zwitter Ion) and L-Ascorbic Acid Assembled via Hydrogen Bonds

Three new complexes, namely [(nicotinic acid)2H] +I-, [(2-amino-6-methylpyridine)H]+ (NO 3)-, and the 1:1 complex between 1-isoquinoline carboxylic acid (zwitter ion form) and L-ascorbic acid were synthesized. The IR spectra revealed different types of hydrogen bonds in these compounds. The X-ray structure determination has shown the first compound to consist of a packing of [(nicotinic acid)2H]+ cations and I – anions. In the dimeric cation the two nicotinic acid molecules (zwitter ions) are connected through hydrogen bonds (O-H…O). Each dimer is further engaged in other hydrogen bonds with adjacent dimers giving 2D layers. The I- ion is located at the inversion center. In the second compound the cation and anion are connected via hydrogen bonds formed between oxygen atoms of the NO3- anion and NH and NH2 of the cation generating a layer structure. All atoms are coplanar on mirror planes. In the 1:1 complex the two molecules are connected through hydrogen bonds formed between the two oxygen atoms of the carboxylate group of 1-isoquinoline carboxylic acid (zwitter ion) and the oxygen atoms of the two adjacent hydrogen groups of the L-ascorbic acid molecule. These complex molecules are engaged in other hydrogen bonds with each other forming a 2D system normal to the long b-axis of the unit cell.
