Studies in Protoberberine Alkaloids: Part XIX – Synthesis of (+/-)-Thalictrifoline, (+/-)-Sinactine and (+/-)-Cavidine

(+/-)-Thalictrifoline (14), (+/-)-sinactine (13) and (+/-)-cavidine (18) have been synthesised from trans- and cis-13-carboxy-9,10-methylenedioxy-2,3-dimethoxy-8-oxo-tetrahydroprotoberberines (8 and 9). 8 and 9 are obtained by condensing 3,4-methylenedioxyhomophthalic anhydride (6) and 6,7-dimethoxyisoquinoline (7).

Asymmetric Hydroarylation of Vinylarenes Using a Synergistic Combination of CuH and Pd Catalysis

Detailed in this Communication is the enantioselective synthesis of 1,1-diarylalkanes, a structure found in a range of pharmaceutical drug agents and natural products, through the employment of copper(I) hydride and palladium catalysis. Judicious choice of ligand for both Cu and Pd enabled this hydroarylation protocol to work for an extensive array of aryl bromides and styrenes, including beta-substituted vinylarenes and six-membered heterocycles, under relatively mild conditions.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.HPLC of Formula: C9H6BrN, you can also check out more blogs about1532-97-4

Suzuki coupling of cyclopropylboronic acid with aryl halides catalyzed by a palladium-tetraphosphine complex

The tetraphosphine all-cis-1,2,3,4-tetrakis(diphenylphosphinomethyl)- cyclopentane (Tedicyp) in combination with [Pd(C3H 5)Cl]2 affords a very efficient catalyst for the coupling of cyclopropylboronic acid with aryl bromides and aryl chlorides. Higher reactions rates were observed with aryl bromides than with aryl chlorides; however, even in the presence of 1-0.4% of catalyst, a few aryl chlorides gave the coupling products in good yields. A wide variety of substituents such as alkyl, methoxy, trifluoromethyl, acetyl, benzoyl, formyl, carboxylate, nitro, and nitrile on the aryl halides are tolerated. The coupling reaction of sterically very congested aryl bromides such as bromomesitylene or 2,4,6-triisopropylbromobenzene also proceeds in good yields. Copyright Taylor & Francis LLC.

Amination of Aromatic Halides and Exploration of the Reactivity Sequence of Aromatic Halides

A base-promoted amination of aromatic halides has been developed using a limited amount of dimethylformamide (DMF) or amine as an amino source. Various aryl halides, including F, Cl, Br, and I, have been successfully aminated in good to excellent yields. Although the amination of aromatic halides with amines or DMF is usually considered as an aromatic nucleophilic substitution (SNAr) process, and the reactivity of an aromatic halide is F > Cl > Br > I, the reactivity of aromatic halides in this system was found to be I > Br a? F > Cl. This protocol also showed a good regioselectivity for multihalogenated aromatics. This protocol is valuable for industrial application due to the simplicity of operation, the unrestricted availability of amino sources and aromatic halides, transition metal-free conditions, no requirement for solvent, and scalability.

Metal-, Photocatalyst-, and Light-Free, Late-Stage C-H Alkylation of Heteroarenes and 1,4-Quinones Using Carboxylic Acids

Contrary to the accepted convention, this work shows that Minisci-type C-H alkylation does not require any metal, photocatalyst, light, or prefunctionalization of the readily available and inexpensive carboxylic acids to proceed well under mild conditions. These mild conditions can be utilized for late-stage alkylations of complex molecules, including pharmaceutical compounds and light-sensitive compounds which degrade under photocatalytic conditions.

Identification of an Imine Reductase for Asymmetric Reduction of Bulky Dihydroisoquinolines

A new imine reductase from Stackebrandtia nassauensis (SnIR) was identified, which displayed over 25- to 1400-fold greater catalytic efficiency for 1-methyl-3,4-dihydroisoquinoline (1-Me DHIQ) compared to other imine reductases reported. Subsequently, an efficient SnIR-catalyzed process was developed by simply optimizing the amount of cosolvent, and up to 15 g L-1 1-Me DHIQ was converted completely without a feeding strategy. Furthermore, the reaction proceeded well for a panel of dihydroisoquinolines, affording the corresponding tetrahydroisoquinolines (mostly in S-configuration) in good yields (up to 81%) and with moderate to excellent enantioselectivities (up to 99% ee).

Base-Mediated Cascade Cyclization: Stereoselective Synthesis of Benzooxazocinone

A new strategy for the synthesis of the oxa-azabicyclo[3.3.1]nonane subunit, a component of the naucleamide E core structure, has been developed. This annulation reaction between 1-substituted 3,4-dihydroisoquinolines and coumarin derivatives conveniently affords the oxa-azabicyclo[3.3.1]nonane framework via a base-mediated cascade cyclization under aqueous conditions. The value of this work lies in the efficient formation of the oxa-azabicyclo[3.3.1]nonane skeleton via a process whereby all the C-C, C-O, and C-N bond formations occur in a single chemical operation. In addition, the subsequent ring opening of these compounds furnished pyridoisoquinoline derivatives.
