✦ Synopsis
Investigations on 1,3‐Thiazines, 43. – Newman‐Kwart Rearrangement in the Course of Thiocarbazoylation of Tetrahydro‐2__H__‐1,3‐thiazin‐2‐one and Thiazolidin‐2‐one
Thiocarbazoylation of tetrahydro‐2__H__‐1,3‐thiazin‐2‐one (1) with thiocarbazic acid chlorides leads to N‐thiocarbazoyl derivatives 5 and N‐carbazoyl‐tetrahydro‐2__H__‐1,3‐thiazin‐2‐thiones 8, which are interpreted as products of an O‐thiocarbazoylation to 6, subsequent Newman‐Kwart rearrangement to 7 and final S→N transcarbazoylation. Thiocarbazoylation of thiazolidin‐2‐one (9) yields an isolable Newman‐Kwart rearrangement product 12 and its product 13 of S→N transcarbazoylation.
