Solid-phase synthesis of optically active substituted 2-aminofuranones using an activated carbonate linker

Matiadis, Dimitris,Prousis, Kyriakos C.,Igglessi-Markopoulou, Olga

, p. 3914 - 3921 (2009)

An efficient three-step solid-phase synthesis of diverse 3,5-disubstituted-2-aminofuranones has been developed. α-Hydroxy acids loaded on a nitrophenyl carbonate derivative of Wang resin are used as acylating agents for the C-acylation of active methylene
