Abstract
Abstract Glycine was acylated with isothiocyanates and condensed to 3-alkyl 2- thiohydantoins, which were reduced with a mixture of sodium borohydride and lithium chloride and dehydrated to 1-alkyl imidazole-2-thiones. These were oxidatively desulfurized to imidazoles with benzoyl peroxide. No chromatography was required for model compounds. The methods developed were used to elaborate tyrosine to 1, 4-di (p- ...
