Synthesis of Cyclic Allylborates from 1,3‐Dienes and a Diboron Reagent

摘要

Abstract The synthesis of cyclic allylborates was achieved by the reaction of 1,3‐dienes and B2pin2 using a copper catalyst. Several 1,3‐dienes were converted to the corresponding cyclic allylborates in moderate to high yields. The cyclic allylborate obtained could be used in several organic transformations such as allylation of electrophiles and Suzuki–Miyaura coupling.
