Asymmetric synthesis of isoquinoline alkaloids

Tetrahedron, 1987
Abstract The use of chiral formamidines affixed to variously substituted tetrahydroisoquinolines, allows asymmetric C-C bond forming reactions to occur α- to the amino group. In this manner, a wide variety of (S)-1-alkyl-1,2,3,4-tetrahydroisoquinolines were constructed in > 90% enantiomeric excess.

The Biosynthesis of Isoquinoline Alkaloids

1985
The tetrahydroisoquinoline skeleton occurs in numerous plant alkaloids. The simplest bearers of this structural unit are exemplified by anhalonidine (12) (Sect. 2). Slightly more elaborate are the benzylisoquinoline alkaloids exemplified at their simplest by reticuline (25) and papaverine (27) (Sect. 3).

Isoquinoline and Benzylisoquinoline Alkaloids

1998
Alkaloids that possess an isoquinoline moiety in their structure are among the most common of all alkaloids. More than 4000 compounds of many structural types but with this structural feature are known (Verpoorte et al., 1991). Those treated in this chapter are all derived from a 3,4-dihydroxytyramine (dopamine) precursor that is linked to an aldehyde ...
