By the reaction with three N,N-dialkylamidosulfenyl chlorides 2 bearing representative sizes for the R groups on the nitrogen atom, several substituted secondary E or Z allylic alcohols (1a-h) have been converted into the corresponding pairs of diastereoisomeric allylic sulfinamides (3+-3′a-v), whose ratios have been determined by 1H NMR spectroscopy. Five cases of entirely diastereoselective [2,3]-sigmatropic
通过与三个N,N-二烷基酰胺基亚磺酰氯2(在氮原子上具有代表性的R基团)反应,一些取代的仲E或Z烯丙基醇(1a-h)已转化为相应的非对映异构烯丙基亚磺酰胺(3 + -3'av),其比例已通过1 H NMR光谱测定。已经观察到五例完全非对映选择性[2,3]-σ重排的情况。

By the reaction with three N,N-dialkylanidosulfenyl chlorides 2 bearing representative sizes for the R group on the nitrogen atom, several substituted secondary propargylic alcohols (la-f) have been converted into the corresponding pairs of diastereoisomeric allenic sulfinamides 3a-n and 3′a-j,l.m. Their ratios have been determined by 1H NMR spectroscopy and were found to depend essentially on the
通过与在氮原子上的R基团具有代表性尺寸的三个N,N-二烷基氨基亚磺酰氯2反应,已将几种取代的仲炔丙醇(Ia-f)转化为相应的非对映异构烯丙亚磺酰胺3a-n和3 'aj,lm。它们的比率已经通过1 H NMR光谱法确定,并且发现其比率基本上取决于起始材料的R 1和R 2基团的大小。一种纯非对映异构体3m的立体化学已通过单晶X射线分析确定。

By the reaction with 4-morpholinesulphenyl chloride carried out in the presence of triethylamine, several substituted allylic alcohols have been converted into the corresponding allylic sulphinamides . As a complementary method, the new lithio-derivatives II have been prepared and efficiently alkylated with organic halides.
