Abstract
Several new homo-and heterocyclic topologically nonplanar organic comp ounds(11, 14, 17-20) with centrohexacyclic (K-5 type) molecular framew orks are described. Besides some centrohexaquinanes comprising five-me mbered rings exclusively ('[5.5.5.5.5.5]centrohexacyclanes'), a number of congeners containing two six or two seven-membered rings have been synthesized for the first time ('[6.5.6.5.5.5]- and [7.5.7.5.5.5]cent rohexacyclanes'). Based on [m.n.o.p]fenestranes, a notation is propose d to define unequivocally the mutual orientation of the various rings. (C) 1998 Elsevier Science Ltd. All rights reserved.
