Synthesis of vinylogous carbamates by rhodium(II)-catalyzed olefination of tertiary formamides with a silylated diazoester
(Chemical Equation Presented) Treatment of tertiary formamides with a silylated diazoester in the presence of a rhodium(II) catalyst leads to the formation of 3-amino-2-silyloxyacrylates in good yield. No olefination is observed if a nonsilylated diazo co
