Design and synthesis of novel, pseudo C2 symmetric inhibitors of HIV protease
摘要:
A novel series of chain-extended, pseudo C2 symmetric 1,5-diaminoalcohol analogs was designed and synthesized using an efficient nitroaldol condensation mediated by triethylsilyl triflate and TBAF.xH(2)O. Prototypical acyclic compounds harboring a central spirolactam or a nitro group, and amide variants of an off-center 1,5-diaminoalcohol analog were synthesized and their activities against HIV protease evaluated.

New chiral (S,E)-gamma-N,N-dibenzylated nitroalkenes 2a-c were synthesized from natural L-(alpha)-amino acids in five steps with overall yields of 68-88%. The conjugate addition of hydride, methoxide, nitronate and azide nucleophiles to 2a-c led to the corresponding chiral 1,3-nitroamines in 74-90% yield. The conjugate addition of cyanide anion to 2a,b was followed by HNO2 elimination affording chiral
