Abstract

Synthesis of New Chiral Pyrylium Salts and Their Phosphinine and Pyridine Derivatives. -Reactions of ketone (I) with acyl chlorides provide new chiral and achiral pyrylium salts. Treatment of the latter with tris(trimethylsilyl)phosphine or ammonium hydroxide results in the formation of phosphinine and pyridine derivatives. -(VAN DER VELDE, N. A.; KORBITZ, H. T.; GARNER*, C.
