Novel base-induced rearrangements of .ALPHA.- and N-halo derivatives of S-ary-S-((1,2-benzisoxazol-3-yl)methyl)sulfoximides to the corresponding N-sulfinylimines.
The title α- and N-halosulfoximides 1-4 undergo base-induced rearrangement reactions to give the same N-sulfinylimines 5, suggesting that these rearrangements all involve the intermediacy of a cyclic sulfoximide, a thiazirine S-oxide 14, which has a novel three-membered ring system with an endocyclic S=N group.
The title N-and α-halogno-sulohoximides (1) and (2) undergo base-induced rearrangement reactions to give the correspondingN-sulphinylimines (3), suggesting the intermediacy of a three-membered cyclic sulphoximide (4) with an endocyclic SN moiety.
标题Ñ -andα-halogno-sulohoximides(1)和(2)经过碱诱导的重排反应,得到相应的Ñ -sulphinylimines(3),这表明三元环状砜酰亚胺(的中间性4与桥环) S N部分。
