Dichloroketene reacts, via a [3,3]-sigmatropic rearrangement, with camphor-derived 1,3-oxathianes of α,β-unsaturated aldehydes to give macrocyclic thiolactones in high yield and with complete transfer of chirality. The rearrangement is stereospecific.
二氯乙烯酮通过[3,3]-σ重排与樟脑衍生的α,β-不饱和醛的1,3-氧杂硫烷反应,以高产率得到大环硫代内酯,并且手性完全转移。重排是立体定向的。
