Titanium-catalyzed enantioselective alkynylation of aldehydes
CHEM. COMMUN., 2002, 172-173,-0001,():
A simple and practical method to make chiral propargylicalcohols has been developed: in the presence of a titaniumalkoxide catalyst prepared in situ from titanium tetraisopropoxideand (R)-H8-binaphthol, a variety of aromaticaldehydes were converted to the corresponding chiralpropargylic alcohols with very good enantioselectivities (upto 96.2% e.e.) and yields.
