A Novel 3,4‐Bis(sulfenyl)‐ or 4‐Selenenyl‐3‐sulfenylpenta‐2,4‐dienylation of Aldehydes Using 4‐Ethoxy‐1,2‐bis(sulfenyl)‐ or 1‐Selenenyl‐2‐sulfenylbuta‐1,3‐dienyl Lithiums.

Abstract

A Novel 3,4-Bis(sulfenyl)-or 4-Selenenyl-3-sulfenylpenta-2,4-dienylation of Aldehydes Using 4-Ethoxy-1,2-bis(sulfenyl)-or 1-Selenenyl-2-sulfenylbuta-1,3-dienylLithiums. -Title reaction is studied with various aldehydes (IV) and used inter alia for the synthesis of the interesting tetraenal (VIII). -(YOSHIMATSU*, M.; MATSUURA, Y.; GOTOH, K.; Chem.
