Abstract
AbstractThe simple and practical syntheses of chiral guanidine organocatalysts and their evaluation in the asymmetric Michael addition reaction of malonates and β‐keto esters with nitro‐olefins is reported. These organocatalysts are the first of their kind based on a tetrahydroisoquinoline framework. In addition, a microwave‐assisted procedure for introducing the guanidine unit onto amino amide derivatives is reported. The chiral products were obtained with quantitative chemical efficiency (up to 99 % yield) and excellent enantioselectivity (up to 97 % ee).
