A versatile and efficient strategy for the total synthesis of the anti‐HIV‐1 agent concentricolide and its analogues daldinins A, B, and C has been established. This strategy offers a mild and facile access to these benzo annulated compounds, bearing multiple stereocenters in good yield with 99% enantiomeric excess (ee) and 93% diastereomeric excess (de) values. Construction of the corresponding syn
已经建立了一种全面有效的抗HIV-1药剂同心内酯及其类似物daldinins A,B和C的通用合成策略。该策略可轻松,轻松地获得这些苯并环氧基化合物,并具有多个立体中心,且产率高,对映体过量(ee)值为99%,对映体过量(de)值为93%。可以通过动态动力学拆分,通过Noyori的不对称转移氢化一步完成相应的顺式二氢苯并呋喃和邻苯二甲酸酯基团的构建。
