Tandem reactions involving 1-silyl-3-boryl-2-alkenes. New access to (Z)-1-fluoro-1-alkenes, allyl fluorides, and diversely α-substituted allylboronates.
摘要：
The reactions of 1-silyl-3-boryl-2-alkenes with various electrophilic reagents (Selecffluor, N-halosuccinimides, benzhydryl, and propargylic alcohols In the presence of a Lewis acid, N-alkoxycarbonyliminium ion) have been investigated as new routes to alpha-substituted allylboronates. Further functional transformations, including allylboration, Suzuki coupling, protodeboronation, and cycloisomerization, have been carried out to illustrate the synthetic potential of these gamma-borylallylsilanes.
