[1]Benzothienoindolizidinones 5ac,ae,bc and [1]Benzothienoquinolizidinone 5ad were synthesized from 2(3)-bromethyl[1]benzothiophene and methyl prolinate, methyl oxoprolinate and ethyl pipecolinate. The Schmidt rearrangement of ketones 5 led exclusively to the [1,3]diazepines derivatives 6.
[1] Benzothienoindolizizidinones 5ac,ae,bc和[1] Benzothienoquinolizidinones 5ad由2(3)-溴甲基[1]苯并噻吩和脯氨酸甲酯,氧代脯氨酸甲酯和哌啶乙酯合成。酮5的施密特重排仅导致[1,3]二氮杂pine衍生物6。
