Calculate Digit Verification of CAS Registry Number 1262117-71:
(9*1)+(8*2)+(7*6)+(6*2)+(5*1)+(4*1)+(3*7)+(2*7)+(1*1)=124

Catalytic silicon-mediated carbon-carbon bond-forming reactions of unactivated amides

Kobayashi, Shu,Kiyohara, Hiroshi,Yamaguchi, Miyuki

supporting information; experimental part, p. 708 - 711 (2011/03/22)

In the presence of catalytic amounts of trialkylsilyl triflate and triethylamine, unactivated amides react with imines to afford the corresponding Mannich-type adducts in high yields with high anti selectivities. While silicon enolates have been widely us
