Nucleophilic ring-opening reactions of 3-aryl-1-benzylaziridine-2-carboxylates were examined by using O-nucleophiles and aromatic C-nucleophiles. The stereospecificity was found to depend on substrates and conditions used. Configuration inversion at C(3) was observed with O-nucleophiles as a major r

The exceptionally bulky methylaluminum bis(4-substituted-2$-di-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 as well as acyclic systems. Thus, Diels-A
