    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

    A method of preparing (+)-calanolide A, 1, a potent HIV reverse transcriptase inhibitor, from chromene 4 is provided. According to the disclosed method, chromene 4 intermediate was subjected to a chlorotitanium-mediated aldol reaction with acetaldehyde to selectively produce (.+-.)-8a. Separation and enzyme-mediated resolution of (.+-.)-8a produced (+)-8a. Cyclization of (+)-8a under neutral Mitsunobu conditions followed by Luche reduction of (+)-7 produced (+)-calanolide A in high yield and enantiomeric purity. The method of the invention has been extended to produce potent antiviral calanolide A analogues.

    extract of Calophyllum lanigerum, along with seven related compounds. In order to examine the structure-activity relationships of the trans-10,11-dimethyldihydropyran-12-ol ring (designated ring C), a series of structural analogues were prepared and evaluated using a whole cell cytopathicity assay (XTT). Removal of the 10-methyl group resulted in decreased activity, with only one epimer exhibiting anti-HIV
    (+)-Calanolide A是一种有效的1型人类免疫缺陷病毒(HIV-1)逆转录酶抑制剂,该酶是从Calophyllum lanigerum的提取物中与7种相关化合物分离得到的。为了检查反式10,11-二甲基二氢吡喃-12-ol环(指定为C环)的结构活性关系,制备了一系列结构类似物并使用全细胞细胞病变试验(XTT)进行了评估。除去10-甲基导致活性降低,只有一种差向异构体表现出抗HIV活性。用乙基链取代10-甲基可保持抗HIV活性,相对于外消旋甘醇二胺A,效力仅降低4倍。用异丙基部分取代10-甲基可完全消除抗HIV活性。在10或11位上添加一个额外的甲基,可以保持母体甘醇内酯体系的基本立体化学特征,同时消除各个碳原子上的手性,但相对于甘醇内酯A而言,活性降低。在所有上述示例中,在10-和11-烷基部分之间具有顺式关系的类似物完全没有活性。12-羟基处于酮氧化态的合成中间体表现出抑制HIV的活性,对于10
