Intramolecular and intermolecular hydroxyl reactivity differences in ginkgolides A, B and C and their chemical applications
摘要：
An investigation of the chemistry of ginkgolides A, B and C ( 1 ) has revealed an unusual interaction between the hydroxyl groups at C(1) and C(10) which activates their deprotonation to give 2 and provides a method for the interconversion of 1C and 1B . The ginkgolide 7-enol system 7 is more stable than the corresponding 7-keto form 6 , which is easily made by selective Jones oxidation of ginkgolide C.
