Abstract

Novel constrained 1-aroyl-cyclopropane-2, 3-cis-dicarboxylic acid bis-[(2-hydroxy-ethyl)- amides](17a–e) with varied torsional angles have been synthesized in high yield from unactivated esters of 1-aroyl-2, 3-cis-diethoxycarbonylcyclopropanes (15a–e) on a catalytic solid support with reduced reaction times by using the monomode-microwave irradiation; 15a–e were obtained by diastereoselective ethoxycarbonylmethylene transfer from a ...
