  Treatment of α-formyl amides with RAlCl2 or PhAlCl2 provided threo-α-alkyl-substituted β-hydroxy amides under high stereocontrol. The method was successfully applied to the selective addition of alkyl group to α-methyl-substituted β-keto amides or esters. Treatment of α-methyl-β-keto amides or α-methyl-β-keto esters with trialkylaluminium or alkylmanganese halide afforded the corresponding erythro (or threo) α-methyl-substituted β-hydroxy amides or α-methyl-substituted β-hydroxy esters with high stereoselectivity.

  An efficient and highly diastereoselective protocol is described for the alkylation of beta-hydroxy ketones that contain an a-stereocenter. This method is based on the preliminary transformation of the beta-hydroxy group into a titanium alcoholate by means of the facile transmetalation of the corresponding beta-silyloxy derivative with TiCl4 (Method A) or by reaction of the lithium alcoholate with TiCl4 (Method B). On account of the strong internal coordinating action of the Lewis acid, this intermediate assumes a rigid half-chair conformation with the alpha-alkyl substituent in a pseudoaxial position, This geometrical arrangement facilitates the attack of the entering carbanion on the carbonylic function apposite to the alpha-substituent. The method uses simple Grignard reagents as the alkylating agents and allows the addition of a wide variety of carbon frameworks to the carbonyl function. including primary and secondary alkyl chains, arylic, alkynylic, vinylic, and benzylic moieties, with high efficiency and stereoselectivity.
