TiCl(4) Promoted Three Component Coupling Reaction : A New Method for the Synthesis of Functionalized Tetrahydrofurans and Tetrahydropyrans

TiC1(4) promoted coupling of ethyl glyoxylate and dihydrofuran or dihydropyran provided oxonium ion intermediates which upon reaction with a nucleophilic trapping agent such as allyltrimethylsilane provided 2,3-disubstituted tetrahydrofurans and pyrans in good yields. The overall protocol constitute...
