  • Tris(pentafluorophenyl)borane, $B(C_6F_5)_3$, was found to be an efficient catalyst for synthesis of N-Cbzhomoallylic amines using Sakurai allylation of N-benzyloxycarbonyl-amino p-tolylsulfones with allyltrimethylsilane.

  • A study on the application of vinyl radical cyclization via free radical allylation reaction in the synthesis of various carbocyclic compounds is described. In connection with this study, a new allyl transfer reagent, 2-bromo-3-(phenylthio)propene 1 is developed and it was shown that vinyl radical cyclization through free radical allylation reaction using reagent 1 provides a valuable approach to carbocyclic systems with a reactive exo-alkylidene moiety, which is advantageous for further transformations.
