摘要
The synthesis of bisbenzopyran-4-ol (1) was performed through the key steps of iodination, nickel(0)-modified Ullmann-type reaction, hydrogen-transfer hydrogenation and diastereoselective reduction. The X-ray diffraction experiment of compound 9 confirmed that the reported structure in the literature was not the real natural product. (C) 2001 Elsevier Science Ltd. All rights reserved.
