  Structure−Activity Modifications of the HIV-1 Inhibitors (+)-Calanolide A and (−)-Calanolide B

  摘要：

  The Delta(7,8) olefinic linkages within (+)-calanolide A (1) and (-)-calanolide B (2) were catalytically reduced to determine impact on the anti-HIV activity of the parent compounds. In addition, a series of structure modifications of the C-12 hydroxyl group in (-)-calanolide B was made to investigate the importance of that substituent to the HIV-1 inhibitory activity of these coumarins. A total of 14 analogs were isolated or prepared and compared to (+)-calanolide A and (-)-calanolide B in the NCI primary anti-HIV assay. While none of the compounds showed activity superior to the two unmodified leads, some structure-activity requirements were apparent from the relative anti-HIV potencies of the various analogs.

  Synthesis of (+)-calanolide A, an anti-HIV agent, Via enzyme-catalyzed resolution of the aldol products

  摘要：

  The synthesis of (+)-calanolide A (1), an anti-HIV-1 agent, is described. A TiCl4-mediated aldol reaction of compound 2 stereoselectively produced the desired syn diastereomer (+/-)-5, which was resolved by a lipase-catalyzed acylation reaction. Under Mitsunobu conditions (Ph(3)P/DEAD), the syn aldol product (+)-5 led to the formation of trans-2,3-dimethyl chroman-4-one [(+)-3] with 94% ee, while the anti aldol product (+)-6 yielded both trans and cis derivatives (+)-3 and (+)-4 with 60% and 68% ee, respectively. Luche reduction on (+)-3 led to (+)-1 and (+)-calanolide B in a ratio of 9 : 1. Copyright (C) 1996 Elsevier Science Ltd
