AlcoholsQ 0230 Rationally Improved Chiral Broensted Acid for Catalytic Enantioselective Allyl-

boration of Aldehydes with an Expanded Reagent Scope. — SnCl4 in combination with the new diol FVO is highly efficient for the asymmetric allylation, methallylation, 2-bromoallylation, and crotylation of aliphatic and aromatic aldehydes. Using this process, an access to naturally occurring (+)-dodoneine (VI) is possible. — (RAUNIYAR, V.; HALL*, D. G.; J. Org. Chem. 74 (2009) 11, 4236-4241; Dep. Chem., Univ.
