A facile asymmetric synthesis of Δ3-2-Hydroxybakuchiol, Bakuchiol and ent-Bakuchiol
摘要:
A facile asymmetric synthesis of Delta(3)-2-Hydroxybakuchiol, Bakuchiol, and ent-Bakuchiol is described through one common intermediate bearing a chiral all-carbon quaternary carbon center, which involves stereoselectively unconjugated alkylation of the alpha,beta-unsaturated imide bearing Evans' auxiliary, Takai-Utimoto reaction, Negishi reaction, and Heck reaction as key steps.
