Synthesis of [6](2,4)pyridinophanes
Abstract
The [6](2,4) pyridinophane derivatives [(11a) and (11b)] have been prepared by treating 4,5,6,7,8,9-hexahydro-1H-cyclo-,octa[b]pyrrole(5b) with dichloro- and dibromo-carbene, respectively. The respective yields of compounds (11a) and (11b) obtained were modest and poor.
