摘要：

Macrocycles 2-3 are synthesized by reacting 2,4-dihydroxybenzophenone with alpha,alpha'-dibromo-p-xylene and then 1,6-diiodohexane. Photoirradiation of 2 yields a new type of cyclophane 5 containing two benzo[b]furan rings via intramolecular delta-hydrogen abstraction. X-Ray analysis shows that 5 has a rectangular cavity of ca. 5.9 Angstrom x7.6 Angstrom. (C) 2000 Elsevier Science Ltd. All rights reserved.
