A one-pot synthesis of alkyl 5-amino-2-mercaptothiazole-4-carboxylates and sulphur-Claisen type rearrangement reactions of the corresponding S-allyl/propargyl compounds
Alkyl 5-amino-2-mercaptothiazole-4-carboxylates (5) have been prepared in a one-pot synthesis by the action of hydrogen sulfide on a mixture of alkyl 2-oximino-2-cyanoacetate and trialkyl orthoformate in pyridine; reduction of the oximino group to imino f
