The conditions were studied o f mono- and diacylation of 7(8)-nitro-2, 3, 4, 5-tetrahydro-1H-1, 5-benzodiazepin-2ones. It was found that under mild conditions (lower temperatures, weak acylating agents), the 7-nitro isomers are acylated only at the 5 -position; increase in the temperature or treatment with an active acylating agent gives the 1,5-diacyl derivatives. Under mild conditions the 8-nitro isomer is not acylated, while under more rigorous conditions a mixture of mono- and diacylated products is formed. |
