(E)-α,β-Unsaturated aldehydes were synthesized by the Julia–Kocienski reaction of 2,2-dimethoxyethyl 1-phenyl-1H-tetrazol-5-yl (PT) sulfone 3 with various aldehydes, followed by acid hydrolysis. The reaction could be carried out in one pot, and various (E)-α,β-unsaturated aldehydes were obtained in a short time and with high yields.
(E)-α,β-不饱和醛是通过2,2-二甲氧基乙基1-苯基-1 H-四唑-5-基(PT)砜3的Julia-Kocienski反应与各种醛合成的,然后进行酸水解。该反应可以在一个锅中进行,并且在短时间内以高收率获得了各种(E)-α,β-不饱和醛。
