the N-Boc hydroxylactam 1–3 is highly diastereoselective and provides 4 in moderate to good yield. Imide ring opening, Curtius rearrangement, and deprotection lead to the desired diamino alcohol core unit 12. A number of substituents, aromatic and heteroaromatic, were included in the R1 and R2 side chains.
HIV-1蛋白酶抑制剂在体外可有效抵抗HIV-1感染的扩散。基于蛋白酶同二聚体的固有对称性,设计,合成并证明了C 2对称和假C 2对称抑制剂是HIV-1蛋白酶的有效抑制剂,可有效阻止HIV-1的传播。体外。我们现在报告伪C 2对称的1,3-二氨基-2-丙醇核心单元12,在这种HIV-1蛋白酶抑制剂中的关键亚基的新型合成。N-Boc羟基内酰胺1–3的二价阴离子的烷基化具有很高的非对映选择性,并提供4中等至良好的产量。酰亚胺开环,Curtius重排和脱保护导致所需的二氨基醇核心单元12。在R 1和R 2侧链中包括许多芳族和杂芳族取代基。
