Gt. Hwang et Bh. Kim, Cyclophane-type bis-calix[4]arenes: efficient synthesis via quadruple cycloadditive macrocyclization and conformational study, TETRAHEDR L, 41(51), 2000, pp. 10055-10060
Cyclophane-type bis-calix[4]arenes were synthesized very efficiently using
quadruple cycloadditive macrocyclization as a key reaction and their confor
mational studies were carried out by solution NMR experiments and X-ray cry
stallography. (C) 2000 Elsevier Science Ltd. All rights reserved.
