非共轭芳烯四炔(4)经热环化得到最终产物(2和10),得到5 H-12-羟基苯并[d]芴并[3,2-B]吡喃自由基(C)和芳基卡宾(D)中间体。观察到DNA链裂解。(C)1998爱思唯尔科技有限公司版权所有。
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.
