We developed a highly stereoselective C-N and C-C bond-forming reaction by carrying out a crystallization-induced dynamic resolution (CIDR) of α-bromo arylacetates followed by a stereoselective substitution reaction with an amine or azlactone nucleophile. Applications of this synthetic method to the preparation of highly enantioenriched nitrogen-containing six-membered heterocycles and α,β-disubstituted aspartates are also presented.

The first enantioselective epoxidation of readily available alkylidenemalononitriles has been developed by using a multifunctional cinchona derived thiourea as the organocatalyst and cumyl hydroperoxide as the oxidant. A new simple one-pot asymmetric epox

experimental part, p. 6221 - 6226 (2011/09/19)
Dynamic resolution of α-halo esters derived from five chiral alcohols has been investigated in nucleophilic substitution with ethylenediamine nucleophiles. Stereoselective substitution of α-halo esters and following spontaneous cyclization provide a pract
