摘要：

New reaction conditions were developed for the synthesis of E,Z-dienes from alpha,beta -unsaturated aldehydes and heteroarylsurfones using the Julia reaction. In most cases under optimal conditions, the selectivity of the olefination reaction is better than 88:12 when a pyridylsulfone was used as the precursor. In addition, novel reaction conditions for the chemoselective oxidation of heteroarylthioethers that are compatible with alkenes and dienes are also reported. (C) 2001 Elsevier Science Ltd.
