J. Guillaumel et al., Synthesis of bis-heteroaryl piperazine derivatives as potential reverse transcriptase inhibitors, J HETERO CH, 38(4), 2001, pp. 985-988
Vinylogous analogs of non-nucleoside reverse transcriptase inhibitors belon
ging to the bis-(heteroaryl)piperazine (BHAP) series were synthesized by co
upling a piperazine derivative with (E)-propenoyl derivatives of heterocycl
ic moieties.
