The novel N,S-substituted halonitrodienes from the reactions of thiosubstituted nitrodiene with piperazine and morpholine

Abstract

The substituted 1,2-dibromomethanethio nitrodiene 2 was obtained from the addition of bromine to S-substituted nitrodien 1 in carbon tetrachloride. N,S-substituted compounds 4a-h were synthesized from the reactions of compound 2 with several substituted piperazine derivatives 3a-h in dichloromethane. N,S-substituted compounds 6 and 8 were synthesized from the reaction of 2 with morpholine (5) and thiomorpholine (7) in dichloromethane, respectively. Dibutadienyl piperazines 10, 12, and 14 were synthesized from the reactions of 2 with homopiperazine (9), piperazine (11), and 2,5-dimethylpiperazine (13), respectively.
