Synthesis of (–)-(R)-angustureine by formal alkynylation of a chiral ß-amino ester

Muñoz*, Gaspar Diaz ; Dudley, Gregory B. ;

Abstract:

The South American angostura tree, Galipea officinalis Hancock, is one of the twenty species of the genus Galipea Aublet. In 1999, Jacquemond described the isolation of tetrahydroisoquinoline alkaloids including angustureine (1, Scheme 1) from the angostura tree bark; antimalarial and cytotoxic properties of this and congeneric alkaloids were later found. The promising biological activity of its alkaloid extracts, and a general interest in tetrahydroisoquinoline synthesis has led to considerable attention on angustureine from the synthetic community.
