An unprecedented arylcarbene formation in thermal reaction of non-conjugated aromatic enetetraynes and DNA strand cleavage
摘要:
The thermal cyclization of non-conjugated aromatic enetetrayne (4) led to the final products (2 and 10) affording 5H-12-hydroxybenzo[d]fluoreno[3,2-b]pyran radical (C) and arylcarbene (D) intermediates. DNA strand cleavage was observed. (C) 1998 Elsevier Science Ltd. All rights reserved.
