Expedite Protocol for Construction of Chiral Regioselectively N-Protected Monosubstituted Piperazine, 1,4-Diazepane, and 1,4-Diazocane Building Blocks
摘要:
This paper describes the first study of solution-phase synthesis of chiral monosubstituted piperazine building blocks from nosylamide-activated aziridines. The protocol, involving aminolysis of the starting aziridines with omega-amino alcohols and subsequent Fukuyama-Mitsunobu cyclization, offers the advantage of mild conditions as well as short reaction times, and it leads to optically Pure N-Boc- or N-Ns-protected piperazines. This four-step sequence, requiring only a single final chromatographic purification, was extended to include novel diazepane and diazocane derivatives.
