Preparation of the zinc enolate equivalent of amides by zinciomethylation of isocyanates: Catalytic asymmetric Reformatsky-type reaction

Haraguchi, Ryosuke,Matsubara, Seijiro

supporting information, p. 2272 - 2282 (2014/12/09)

Bis(iodozincio)methane [CH2(ZnI)2] transforms isocyanates (R-N=C=O) into the enolate equivalent of amides via zinciomethylation. The reactivity of the enolate equivalent as a nucleophile toward aldehydes depends on the R group of the
