Novel Functionalized Trisubstituted Allylboronates via Hosomi−Miyaura Borylation of Functionalized Allyl Acetates
摘要:
A series of novel functionalized achiral and chiral allylboronates have been synthesized via the nucleophilic addition of boronates on allyl acetates derived via vinylalumination or Baylis-Hillman reaction of aldehydes. These reagents, upon allylboration with aldehydes, furnish,beta-substituted-alpha-methylene-gamma-butyrolactones stereoselectively.
