New transient arenesulfenic acids were involved in the synthesis of enantiopure 2-arylsulfinyl-1,3-dienes, showing central or axial chirality of the substituted arene residue, apart from the chirality related to the stereogenic sulfur atom. Some of the obtained dienes, that is, (Sa,SS)- and (SaRS)-2-(2′-hydroxy-1,1′-binaphthalen-2-sulfinyl)-3-methyl-1,3-butadienes, were subjected to diastereoselective
新的瞬时芳烃亚磺酸参与了对映体纯的2-芳基亚磺酰基-1,3-二烯的合成,除了与立体异构硫原子相关的手性外,还显示了取代的芳烃残基的中心或轴向手性。获得的一些二烯,即(S a,S S)-和(S a R S)-2-(2'-羟基-1,1'-联萘-2-亚磺酰基)-3-甲基-1 ,3-丁二烯与N-甲基马来酰亚胺进行非对映选择性Diels-Alder环加成反应。通过用阮内镍还原裂解来除去主要加合物中的芳基亚砜助剂。
