3382-18-1, Name is 6,7-Dimethoxy-3,4-dihydroisoquinoline, belongs to isoquinoline compound, is a common compound. Product Details of 3382-18-1In an article, once mentioned the new application about 3382-18-1.
The tetrahydroprotoberberine alkaloids (+)-thalictricavine <(+)-6> and (+)-canadine <(+)-23> have been synthesized from an optically resolved (+)-13-carboxy-7,8,13,14-tetrahydro-9-oxoprotoberberine <(+)-26>.This establishes the absolute configuration of (+)-thalictricavine as 13S,14R. (+)-Thalictrifoline <(+)-2> and (+)-cavidine <(+)-1> have also been prepared from a common intermediate, (+)-32, whose absolute configuration was established by correlation with (+)-26.This determines the absolute configuration of (+)-thalictrifoline as 13R,14R, of (+)-corydalic acid methyl ester (22) as 3R,4R, and of the protopine (+)-corycavine (20) as 13R.
