[摘要]:A series of chalcones 3a-d containing phenothiazine nucleus were prepared by Claisen-Schmidt condensation. The chalcones on treatment with urea, thiourea, phenyl urea, and phenyl thiourea in alcoholic KOH yielded compounds 4a-p, and the structures of these compounds were confirmed by spectral and elemental analyses. The newly synthesized compounds were evaluated for antimicrobial activity. |
