Regioselectivity in the schmidt reaction: First synthesis of pyrano[3,2-b]azepines

The Schmidt reaction of 5,6,7,8-tetrahydro-2H-1-benzopyran-2-ones (1) has been investigated. Derivatives of pyrano[3,2-c]azepines (2) and isomeric pyrano[3,2-b]azepines (3) were isolated by the application of trimethylsilyl azide or sodium azide in a meth

Pyranoazepine, a new heterocyclic system. A new approach to pyridoazepines

3-Benzoylamino-7,7-dimethyl-5-oxo-5,6,7,8-tetrahydrocoumarin (1a) was used as a synthon in the preparation of the first derivatives of the pyranoazepine system 2 and in two approaches to pyridoazepines 4.
