Abstract
1. Albonoursin is 3-benzylidene-6-isobutylidene-2,5-piperazinedione. 2. A natural analog of albonoursin was isolated from the mycelia ofActinomyces albus var. fungatus andA. noursei, a number of its chemical properties were studied, and it was shown that it is 3,6-dibenzylidene-2,5-piperazinedione. 3. The cleavage of 3,6-dibenzylidene-2,5-piperazinediones and albonoursin under the action of electron impact was studied, and a general scheme for the fragmentation of these compounds was established. 4. The halogenation of albonoursin and its analog was studied, and it was shown that substitution in the methine groups occurs.
