Enantioselective total synthesis of ginkgolide derivatives lacking the tert-butyl group, an essential structural subunit for antagonism of platelet activating factor
摘要:
An enantioselective total synthesis of the ginkgolide B analog 3 is reported along with the results of bioassays for antagonism of platelet activating factor. The three orders of magnitude difference in bioactivity of 2 and 3 demonstrates that the tert-butyl group of the ginkgolides is essential for anti-PAF potency.
