摘要

Abstract A new synthesis of deoxysepiapterin (2), one of the two yellow eye pigments of the Drosophila mutant sepia, is described. The synthetic approach makes use of a homolytic nucleophilic acylation of 7-(alkylthio) pteridine derivatives (11, 13, 15, 18, 20) leading to the corresponding 6-acyl derivatives (21–27). Desulfurizations have been achieved for the first time in the pteridine series using Raney-Co, Raney-Cu, or Cu [BOND] Al alloy in alkaline ...
