A SIMPLE ENTRY TO FUSED N-ARYL 1,2-THIAZETIDINE-S-OXIDES - THERMAL-ISOMERIZATION TO 1,4-THIAZINE-S-OXIDES AND NUCLEOPHILIC RING-OPENING WITH ALCOHOLS AND AMINES
Rn. Warrener et As. Amarasekara, A SIMPLE ENTRY TO FUSED N-ARYL 1,2-THIAZETIDINE-S-OXIDES - THERMAL-ISOMERIZATION TO 1,4-THIAZINE-S-OXIDES AND NUCLEOPHILIC RING-OPENING WITH ALCOHOLS AND AMINES, Synlett, (2), 1997, pp. 167
We show that fused 1,2-thiazetidine-S-oxides can be produced in one st
ep from readily available aryl sulfonylamines by cycloaddition with qu
adricyclane; these adducts undergo smooth rearrangement to fused 1,4-t
hiazines-S-oxides on heating, and can be ring-opened with alcohols to
form cis-1,2-arylamino sulfinic eaters and cis-1,2-arylamino sulfinami
des on treatment with amines.
