Back Cover: Asymmetric Synthesis of the Ring A Substructure of Genkwadane A (Chin. J. Chem. 9/2018)
Abstract:
The back cover picture shows Genkwadane A was isolated from the flower buds of Daphne genkwa which shows bioactivity against HeLa, HepG2, HT‐1080, MCF‐7, A549, U‐937, K562 and HL60 cell lines. It is the first time that a daphnane diterpenoid bearing a 1,10‐double bond was isolated. In this paper, B. Liu and co‐workers report asymmetric synthesis of the ring A substructure of genkwadane A in 10 steps from D‐tartrate derivative. More details are discussed in the article by Liu et al. on page 831–836.
