摘要

Cycloaddition of 1,3-oxazol-5-ones (2) to 2-phenylbenzazete (1 ) gives 3H-1,3- benzodiazepines (4) which undergo thermal rearrangement to 3H-indoles. ... There are only isolated reports of 5H-1 and 3H-benzo-1,3- diazepines2 and the first 1H-derivatives have recently been obtained by photolysis of isoquinoline N-imide~.~ We now report that 1,3-dipolar cycloaddition of 1,3-oxazo1-5-ones (munchnones) (2) to 2-phenylbenzazete (1) provides a simple route to ...
