摘要

The mono-C-methylation of arylacetonitriles (ArCH2-CN, 1) to produce 2-arylproprionitriles [ArCH (CH3) CN, 2] represents a valuable reaction especially from a pharmaceutical standpoint. In fact, a number of compounds 2 are key intermediates for the synthesis of nonsteroidal analgesics of the hydratropic acid (2-arylpropanoic acid) class. 1 Common well- known examples are Ibuprofen, Ketoprofen, and Naproxen (Chart 1). However, synthetic ...
