Biosynthesis of tuberin and xanthocillin from tyrosine

Tetrahedron Letters

Abstract

(2S)-Tyrosine (5) is incorporated stereospecifically into tuberin (1) with retention of the 3-pro-S proton and incomplete retention of the 2-S proton; a parallel pathway to the xanthocillin (4) is apparent with stereospecific retention of the 3-pro-R proton of tyrosine; results of experiments with threo- and erythro-3-hydroxytyrosine in relation to tuberin biosynthesis are reported.
