Phenylphosphinic Acid-Promoted Addition of Isocyanide to 1-Methoxyisochroman Derivatives
摘要:
A synthetic method for preparation of isochroman-1-carboxylamides in good to high yields by addition of isocyanides to 1-methoxyisochroman derivatives in the presence of phosphinic acid was developed. A wide range of 1-methoxyisochroman derivatives and isocyanides were suitable for this reaction.
