"In the presence of a catalytic amount of bismuth triflate, methyl 3-acetoxy-3-aryl-2-methyl-enepropanoates and 3-acetoxy-3-aryl-2-methylenepropanitriles were smoothly converted into methyl (2E)-2-(acetoxymethyl)-3-arylprop-2-enoates and (2E)-2-(acetoxymethyl)-3-arylprop-2-enenitriles, respectively," scientists writing in the journal Geological Magazine report. "A remarkable reversal in stereochemical directions from ester to nitrile was observed. 3-Aryl-3-hydroxy-2-methylenepropanoates and 3-aryl-3-hydroxy-2-methylenepropanitriles could be easily obtained as Baylis-Hillman adducts from methyl acrylate and acrylonitrile, respectively. The overall process is an...
