从不同的起始原料不对称合成了四个异构的甲基取代的DCK类似物(2-5)。3-甲基,4-甲基和5-甲基-3',4'-二-O-(-)-樟脑酰基-(+)-顺式-甲壳酮(2-4)对HIV-1复制都非常有效H9淋巴细胞中的EC50值分别为<4.23 x 10(-7)microM和> 3.72 x 10(8),这比本实验中DCK和AZT的要好得多。

report a novel strategy for the design and construction of natural and natural product-like librariesbased on the principle of privileged structures, a term originally introduced to describe structural motifs capable of interacting with a variety of unrelated molecular targets. The identification of such privileged structures in naturalproducts is discussed, and subsequently the 2,2-dimethylbenzopyran

Convenient two-step approaches are described for the syntheses of seselin (3a), seselin and angelicin derivatives (3b–d and 5a–d) from 2,4-dihydroxybenzaldehyde (1a) and 2,4-dihydroxyacetophenone (1b) using tandem Claisen rearrangement and Wittig reaction.
