Reddy, Leleti Rajender
supporting information; experimental part, p. 9189 - 9191 (2012/09/22)
A versatile and highly enantioselective chiral Bronsted acid-catalyzed allenylation of aldehydes with propargyl borolane is reported. The reaction is shown to be practical and quite general with a broad substrate scope covering aryl, heteroaryl, α,β-unsaturated, and aliphatic aldehydes.
The silylalkyne-prins cyclization: Stereoselective synthesis of tetra- and pentasubstituted halodihydropyrans

A new type of Prins cyclization using silylated secondary homopropargylic alcohols and aldehydes yielding tetra- and pentasubstituted dihydropyrans is described. The presence of the trimethylsilyl group in the triple bond favors the Prins cyclization and
