Oxazepines and Thiazepines XXXVII [1]. A Simple and Convenient Procedure for the Preparation of 3-Acyl-2,3-dihydrobenzothiazoles by Ring Contraction of 2,4-Diaryl-2,3-dihydro-1,5-benzothiazepines under Acylating Conditions
摘要:
3-Acyl-2,3-dihydrobenzothiazoles 13-30 were prepared by ring contraction of 2,4-diaryl-2,3-dihydro-1,5-benzothiazepines 1-12 under acylating conditions. This procedure provides a general and efficient access to these benzothiazole derivatives.
