  摘要：

  研究了在各种压力（1 bar-6 kbar）下，抗人类免疫缺陷病毒（抗HIV）碳环腺嘌呤核苷9-[c-4, t-5-双（羟甲基）环戊-2-烯-r-1-基]-9H-腺嘌呤（BCA）的脱氨作用。 研究发现，虽然（+）-BCA几乎没有受到影响，但在4 kbar的压力下，对（-）-BCA的脱氨作用显著增强，产生了相应的（-）-次黄嘌呤衍生物（（-）-BCH），ee值接近100%。

  Synthesis and anti-HIV activity of 9-[c-4,t-5-bis(hydroxymethyl)cyclopent-2-en-r-1-yl]-9H-adenine

  摘要：

  The synthesis and in vitro anti-HIV activity of two new racemic nucleoside analogues are described; namely, 9-[c-4,t-5-bis(hydroxymethyl)cyclopent-2-en-r-1-yl]-9H-adenine (12) and its guanine analogue 18. While the latter (18) showed no activity, the therapeutic index of the former (12) was 200 and comparable to that (400) of carbovir. One enantiomer of 12 may be viewed as an analogue of carbocyclic oxetanocin and the other as an analogue of carbovir. Hence, these results indicate that one or both of the individual enantiomers of 12 could serve as candidates or lead compounds for the development of anti-AIDS agents.

  norbornadienes were stereoselectively converted into the meso-3,5-bis(acetoxymethyl)cyclopentenes by a three-step sequence of ozonolysis, reduction, and acetylation. Rhizopus delemar lipase (RDL)-catalyzed asymmetric hydrolysis of meso-3,5-bis(acetoxymethyl)cyclopentenes afforded the monoalcohols of high enantiomeric purities (>95% ee) in good yields (64-95%). The obtained monoalcohols 11 and 14 could be

  (1R,4S,5R)-9-(4,5-Bishydroxymethylcyclopent-2-en-1-yl)-9H-adenine [(-)-BCA] has been synthesized from (-)-Corey lactone in 11 steps and shown to have potent and selective effects against human immunodeficiency virus type 1. The result demonstrated that the potent-HIV activity of racemic BCA obtained in our previous work is expressed solely by the (1R,4S,5R)-(-)-isomer.

  Stereoselectivity of the cis-dihydroxylation of cis-3, 5-disubstituted cyclopentenes has been found to depend on the conformation of cyclopenetenes and has been explained by both steric and Cieplak effects.
