Iodine mediated one-pot synthesis of 3-cyano and 3-cyano-4-methylcoumarins

2-Hydroxybenzaldehydes 1a-e on reaction with malononitrile 2 in the presence of iodine as catalyst give 3-cyanocoumarins 3a-e in one step under thermal heating as well as microwave irradiations. The latter conditions are much more efficient in terms of time (2-5 minutes) and yield as compar...
