Synthesis of batracylin and its N-sulfonamido analogues in [b-3C-im][NTf2] ionic liquid
摘要:
Starting with commercial and inexpensive reagents, a high-yielding chemical process carried out in [b-3C-im][NTf2] ionic liquid was achieved to afford the synthesis of batracylin and its N-sulfonamido analogues. Among all compounds synthesized, compounds 1, 11, and 14 exhibit potent inhibitory activity against human topoisomerase 1 (hTop1). (C) 2014 Elsevier Ltd. All rights reserved.
