Three New Diels-Alder Type Adducts from the Roots of Sorocea bonplandii Baillon
摘要:
Three new ketalized Diels-Alder type adducts named soroceal (1), sorocein A (2), sorocein B (3), were isolated from the methanolic extract of the roots of Sorocea bonplandii. The structures were assigned on the basis of chemical and spectroscopic evidences.
