Al0 for the allylation of a variety of prostereogenic α,α-disubstituted (hindered) cycloalkanones, 1,2-dione-based systems and various imino systems (CN functional groups) is reported. The stereoselective InCl3-catalyzed Al-based allylation of various 2-substituted-2-carbethoxycycloalkanones gave the corresponding products with moderate to excellent diastereoselectivity. The allylation and propargylation

日期:——
acid-catalyzed highly diastereoselective asymmetric Friedel–Crafts alkylation of arenes with a chiral N-tert-butanesulfinylimino ester is described. The reaction can be accomplished with ease in the presence of a catalytic amount of In(OTf)3 at room temperature, providing a series of enantiomericallyenriched α-arylglycines in good yields and with excellent diastereoselectivities (up to 99% de). Highly stereoselective

Asymmetric Synthesis of α-(Diarylmethyl) Alkyl Amines through Regioselective Lithiation of α-Diarylmethanes and the Diastereoselective Addition to Ellman’s Imines
A highly regio- and diastereoselective lithiation/addition of α-diarylmethanes to N-tert-butanesulfinylimines is reported. This methodology also affords the preparation of enantiomerically pure α-(diarylmethyl) alkyl amines bearing quaternary centers.
