Novel Analogues of Tiazofurin by Lawesson Reagent Effected Cyclization
摘要:
2-Benzylthiazole-4-carboxamide 4 and 5-(beta-D-ribofuranosylamino) thiazole-4-carboxamide 10 were synthesized from phenylacetylamino- and formylamino cyanoacetic acid esters 1a and 1b,respectively. The ribosylation reaction leading to 10 gave rise also to its alpha anomer as a minor product.
