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
