2-Thiazoline-4-carboxylic acid
Abstract
Ring-closure of N-formylcysteine in acid solution affords 2-thiazoline-4-carboxylic acid, the simplest thiazoline derivable from cysteine. The behaviour of this thiazoline in acid and in buffered aqueous solutions has been studied spectrophotometrically. Related observations on 2-phenyl-2-thiazoline-4-carboxylic acid are also recorded.
