摘要

In the course of our study on neurotoxic C17-polyacetylenic alcohols of the toxic plant, Cicuta virosa, virols A (1), B (2), and C (3) were synthesized by stereoselective routes to confirm their stereochemistry and to obtain supply of these compounds for pharmacological study. The syntheses used chiral 3-hydroxy-1-alkyne building blocks, Pd (0)-CuI (I)- catalyzed coupling of acetylene with vinyl chloride, and heterocoupling reaction of ...
