Novel reactions of 6,7-dimethoxy-3,4-dihydroisoquinoline and 3,4-dihydro-beta-carboline with dipolarophiles

New reactions of 6,7-dimethoxy-3,4-dihydroisoquinoline and 3,4-dihydro-beta-carboline with various electron-deficient olefins are described. ‘One-pot’ generation and cycloaddition of the 1,3- and 1,4-dipoles formed from these heterocycles with a range of alkene dipolarophiles affords cycloadducts in good yields with high regio- and stereoselectivity.

Xylochemistry – Making Natural Products Entirely from Wood

The first total synthesis of the dimeric berberine alkaloid ilicifoline (ilicifoline B) is reported. Its carbon skeleton is constructed from ferulic acid, veratrole, and methanol. The synthesis reported herein employs starting materials solely derived from wood. The natural product is thus constructed entirely from renewable resources. The same strategy is applied to a formal total synthesis of morphinan alkaloids. The use of wood-derived building blocks (xylochemicals) instead of the conventional petrochemicals represents a sustainable alternative to classical synthetic approaches.

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.Computed Properties of C11H13NO2, you can also check out more blogs about3382-18-1

Dual promiscuous racemization/amidation activities of lipases leading to efficient dynamic kinetic resolution protocols of racemic alpha-aminonitrile compounds are described. alpha-Amidonitrile products of high enantiomeric purity could be formed in high yields. Several lipases from different sources were shown to exhibit the dual catalytic activities, where opposite enantioselectivities could be recorded for certain substrates.

INTERMEDIATES USEFUL FOR MAKING TETRABENAZINE COMPOUNDS

A method of preparing a tetrabenazine compound (TBZ compound) having structure I comprising the steps of reacting a nucleophilic alkenyl species with aldehyde compound II and oxidizing the resultant allylic alcohol to provide enone III. The protecting group P1 on the tetrahydroisoquinoline nitrogen is removed and the resultant deprotected intermediate is induced to undergo an amino cyclization reaction to provide a product TBZ compound having structure I. The method may be used to prepare either enantiomeric form of tetrabenazine; (+)-tetrabenazine or (?)-tetrabenazine. Alternatively the method may be adapted to provide a mixture enriched in one tetrabenazine enantiomer, a racemic mixture, or a diastereomeric mixture of tetrabenazine compounds. In addition, the present invention provides novel synthetic intermediate compositions which may be used to prepare either or both enantiomers of tetrabenazine, derivatives of tetrabenazine, and analogs of tetrabenazine.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 3382-18-1 is helpful to your research. Reference of 3382-18-1

One-pot, three-step copper-catalyzed five-/four-component reaction constructs polysubstituted oxa(thia)zolidin-2-imines

A novel one-pot synthesis of polysubstituted oxa(thia)zolidin-2-imines has been developed. It employs A3-coupling of aldehyde and amine with alkyne to form propargyl amine, which on (thio)amidation with iso(thio)cyanate produces N-propargyl(thio)urea, and a cyclization reaction. A 5-exo-dig iodocyclization of N-propargylurea constructs 5-iodomethyleneoxazolidin-2-imine, while cycloisomerization of the thio analogue provides 5-methylenethiazolidin- 2-imine. In this process, CuI catalysis has been found to be crucial, and the cyclization occurs through oxygen/sulfur (not nitrogen) nucleophilic attack to alkyne. Georg Thieme Verlag Stuttgart ¡¤ New York.

One-step synthesis of complex nitrogen heterocycles from lmines and alkyl-substituted maleic anhydrides

Substituted maleic anhydrides react with imines to form poly cyclic lactam products. Diastereoselectivity can be controlled by altering the reaction conditions in some cases, and regiochemistry is dictated by the structure of the allylic substituents on the anhydride. Cyclic imines, including dihydro-beta-carbolines and dihydroisoquinolines, exhibit the highest level of reactivity in these new annulation reactions.
