OXOLANE-2,2 prime -PIPERAZINE.

The compound 3-(3-hydroxy)propylidene-piperazine-2,5-dione, derived from ethyl 4-ethoxycarbonyl-2-chloroacetylamino-2-butenoate, was treated with N-bromosuccinimide (NBS) in chloroform to give the spiro- left bracket oxolane-2,2 prime -piperazine right br

FACILE SYNTHESES OF 3-SPIRO- AND 3,6-BRIDGED 2,5-PIPERAZINEDIONES

The intramolecular addition of hydroxyl group of 3-(3-hydroxyl)propylidene-2,5-piperazinedione to 3-position and the same substitution of 3-(3-hydroxy)propyl derivative to 6-position gave the corresponding 3-spiro- and 3,6-bridged 2,5-piperazinediones, re
