Hc. Lin et al., SYNTHESIS OF 3,11-DIOXATETRACYCLO[6.3.0.0(2,6).0(5,9)]UNDECANES AND XAPENTACYCLO[7.2.1.0(2,8).0(4,11).0(6,10)]DODECANE, Journal of the Chinese Chemical Society, 44(6), 1997, pp. 609-616
The synthesis of 3,11-dioxatetracyclo[6.3.0.0(2,6).0(5,9)]undecanes ha
s been accomplished from furans in a short sequence by iodine-induced
cyclization reaction. The application of iodine-induced cyclization re
action for the synthesis of xapentacyclo[7.2.1.0(2,8).0(4,11).0(6,10)]
dodecane itself was also demonstrated.
