Efficient synthesis of N1- or N3-substituted thieno[2,3-d]imidazol-2-ones
摘要:
N-1- or N-3-substituted thieno[2,3-d]imidazol-2-one derivatives are selectively obtained after N-alkylation of thiaisatoic anhydrides followed by formation of the N-substituted aminocarbonyl azides and Curtius rearrangement, (C) 1999 Elsevier Science Ltd. All rights reserved.
