Quinolinecarboxylic acid reductive decarboxylation

The photolysis of 0-acyI benzophenone oximes in isopropyl alcohol in the presence of r-butyl thiol leads to overall reductive decarboxylation. Yields for simple aliphatic and amino acids are reported to be good. It is especially noteworthy that reductive decarboxylation of 2- and 4-quinolinecarboxylic acids (although not of the 3-isomer, nor 1- or 2-naphthalenecarboxyIic acids) was achieved in moderate yield by this method (equation 9).
