| abstract |
The present invention provides methods for preparing 2-alkylcysteine derivatives, many of which can be performed stereoselectively. The present invention also discloses a process for the preparation of a class of ion chelators for desferrithiocin, all of which contain a thiazoline ring, examples of these ion chelators being 4,5-dihydro-2- (2, 4,5-dihydro-2- (2,4-dihydroxyphenyl) -4-alkyl-thiazole-4-carboxylic acid such as 4-dihydroxyphenyl) -4-methyl-thiazole-4-carboxylic acid. |
