The exceptionally bulky methylaluminum bis(4-substituted-2,6-di-tert-butylphenoxide) such as MAD or MABR can be successfully utilized as a highly efficient nonchelating Lewis acid for achieving high stereoselectivity in 1,n asymmetric induction in cyclic

An optimum reaction system is described for the highly stereoselective addition of carbanionic nucleophiles to chiral α-alkoxyketones.A variety of oxygen protecting groups are acceptable and allow chelation-controlled α-asymmetric induction with diastereo
