A novel entry into 1,2,3,4,5,6-hexahydro-3-benzazocine-4,6-dione and 2-substituted-2,5,6,7-tetrahydro-4-benzazonine-1,3-(4H)-dione
摘要:
2-Substituted-1,2,3,4,5,6-hexahydro-3-benzazocine-4, 6-diones(1a-d) and 2-methoxy-2,5,6,7-tetrahydro-4-benzazonine-1,3 -dione 8 were synthesised through an oxidative ring expansion reaction of 6-methylthio-7-substituted-benzo[a]octem (2a-d) and 7-methylthio-8-methoxy-benzo[a]nonem 7 with sodium periodate in isopropanol respectively.
