Enantioselective 1,4 Addition of Aldehydes to Nitrodienes
Belot and coworkers have recently demonstrated an enantioselective 1,4-addition of aldehydes to nitrodienes using a diphenylprolinol silyl ether organocatalyst. The reaction is feasible with a variety of substituted aldehydes and nitrodienes providing the 1,4-adduct with good levels of diastereo- and enantiocontrol using low loadings of (S)-(–)-alpha,alpha-diphenyl-2-pyrrolidinemethanol trimethylsilyl ether.
