The reaction between prop-2-yne-1-sulphonyl chloride and α-morpholinostyrene was performed (a) in the presence of an equimolar amount of triethylamine at 0° to give 4-acetyl-3-phenyl-2H-thiet 1,1-dioxide (7) and 1-morpholino-1-phenyl-3-thiahex-1-en-5-yne 3,3-dioxide (3) or the corresponding 3-thiahex-1-en-5-one dioxide (6), depending on the work-up conditions; and (b) at –30° with triethylamine and
丙-2-炔-1-磺酰氯与α-吗啉代苯乙烯之间的反应(a)在等摩尔量的三乙胺的存在下于0°进行,得到4-乙酰基-3-苯基-2 H - thiet 1, 1-二氧化物(7)和1-吗啉代-1-苯基-3-硫杂1--1--5-炔3,3-二氧化物(3)或相应的3-硫杂-1--1--5-二氧化物( 6),取决于后处理条件;(b)在–30°时与三乙胺和磺酰氯以3:1的比例混合,得到3-吗啉代-3-苯基-2-乙烯基偏二乙炔1,1-二氧化物(11)和开链砜(6)。讨论了产品的来源。化合物(11)和1-吗啉代-1-苯基-3-硫杂六-1,4,5-三烯3,3-二氧化物(10)被证明是砜(7)和(6)的可能前体,分别。
