Enantioselective alkylations of tributyltin enolates catalyzed by Cr(salen)Cl: Access to enantiomerically enriched all-carbon quaternary centers: Enantioselective alkylations of tributyltin enolates catalyzed by Cr(salen)Cl: Access to enantiomerically enriched all-carbon quaternary centers. Doyle, Abigail G.; Jacobsen, Eric N. (Department of Chemistry and Chemical Biology, Harvard University, Cambridge, MA 02138, USA). Journal of the American Chemical Society, 127(1), 62-63 (English) 2005 American Chemical Society. CODEN: JACSAT. ISSN: 0002-7863. 164931-83-3 and 244633-46-3 are also in the experiment. DOCUMENT TYPE: Journal CA Section: 24 (Alicyclic Compounds) The catalytic asym. a-alkylation of tributyltin enolates with a range of primary alkyl halides was catalyzed by a chiral Cr(salen) complex. The reaction constitutes an example of transition-metal-catalyzed a-alkylation of carbonyl substrates with electrophiles, providing access to five-, six-, and seven-membered ring ketone products bearing a-quaternary stereocenters in high enantioselectivity and synthetically useful yields. .
