Visible light irradiation of N-bromosuccinimide serves as an effective means to convert methyl 2-(azidomethyl)-3-arylpropenoates and 2-(azidomethyl)-3-arylacrylonitriles to the corresponding iminyl radicals via ?±-hydrogen abstraction and subsequent extrusion of dinitrogen. Thus formed iminyl radicals then undergo intramolecular ortho attack on the aryl ring, affording methyl quin-oline-3-carboxylates and quinoline-3-carbonitriles respectively.

A new strategy was developed for the synthesis of a valuable class of α-aminomethylacrylates via the Baylis-Hillman reaction of different aldehydes with methyl acrylate followed by acetylation of the resulting allylic alcohols and SN2′-type amination of the allylic acetates. Asymmetric hydrogenation of these diverse olefinic precursors using rhodium(Et-Duphos) catalysts provided the corresponding β2-amino acid derivatives with excellent enantioselectivities and exceedingly high reactivities (up to >99.5% ee and S/C=10,000). The first hydrogenation of (Z)-configurated substrates was studied for the synthesis of β2-amino acid derivatives. The high influence of the substrate geometry and steric hindrance on the reactivity and enantioselectivity was also disclosed for this reaction. This protocol provides a highly practical, facile and scalable method for the preparation of optically pure β2- amino acids and their derivatives under mild reaction conditions.
