In heterogeneous catalysis, the catalyst is in a different phase from the reactants. Application In Synthesis of 6,7-Dimethoxy-3,4-dihydroisoquinoline, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 3382-18-1, name is 6,7-Dimethoxy-3,4-dihydroisoquinoline. In an article，Which mentioned a new discovery about 3382-18-1
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.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 3382-18-1, help many people in the next few years.Application In Synthesis of 6,7-Dimethoxy-3,4-dihydroisoquinoline
