ABSTRACT:
Benzimidates can be reacted with a large number of nucleophiles, leading to a wide variety of products. The present invention discloses a facile synthesis for ethyl 2,4-dihydroxybenzimidate, and ethers and diethers thereof, from 2,4-dihydroxybenzoic acid or 2,4-dibenzyloxybenzoic acid. The present invention also discloses a method of preparing a class of iron chelating agents related to desferrithiocin, all of which contain a thiazoline ring. In this method, 2,4-dihydroxybenzonitrile is condensed with (S)-2-methylcysteine.
