A novel and facile synthesis of substituted 2,3-dihydro-1,4-dithiins and 6,7-dihydro-5H-1,4-dithiepins based on the reactions of α-bromo/hydroxy ketones with α-oxo ketenecyclicdithioacetals has been developed. A general mechanism for the reactions is proposed.
基于α-溴/羟基酮与α-氧代乙烯酮环的反应,可轻松合成新颖的取代的2,3-二氢-1,4-二硫辛和6,7-二氢-5 H -1,4-二硫平已开发出二硫缩醛。提出了反应的一般机理。
