Yatiaroic acids A–C, three novel seco-serratane triterpenoids from Myrica gale var. tomentosa
摘要
Three novel triterpenoids, yatiaroic acids A–C (1–3) with an unprecedented seco-serratane skeleton were isolated from branches of Myrica gale var. tomentosa. The relative and absolute stereochemistry of 1–3 were determined on the basis of the 2D NMR data, chemical transformation, and CD calculation.
