摘要：

The reaction of nitroalkanes with 2-chloro-3-phenylsulfonylpropanenitrile, in the presence of three equivalents of DBU at -10degreesC, allows the synthesis of polyfunctionalized alpha,beta-unsaturated nitrites. The method proceeds through three different reactions carried out in a tandem sequence, allowing the one-pot formation of the alpha,beta-unsaturated nitrites, generally, with complete E stereochemistry.
