For regiospecific alkylation of kinetic enolates of cyclic /3-diketone enol ethers, see G. Stork and R. L. Danheiser, J. Org. Chem., 38, 1775 (1973). [Pg.287]

Medium-sized cyclic ketones have been enantioselec-tively alkylated via their chiral lithioenamines to yield 2-alkylcycloalkanones in 80-100% ee. This procedure has also furnished a,a -dialkyl cyclohexanones in good enantiomeric excess (eq 2). Based on this protocol, regiospecific deutera-tion of 3-methylcyclohexanones has been achieved with good enantioselectivity. ... [Pg.56]

Reductive sulfeuyiation. Gassman et al. have found that] Stork s method for reductive alkylation of a,/3-unsaturated ketones (1, 601-602) is applicable to reductive sulfenylation of cyclic a, 3-unsaturated ketones and has the advantage of regiospecificity in the formation of ra-methylthio ketones. Furthermore, the reaction proceeds with some preference for axial attack. [Pg.404]
