Abstract

2% R= CHJ 3a, x= ob, R= CO, H dates to possess a folded conformation or “butterfly conformation” when CXC and CYC angles deviated significantly from 120. 3 Thus, heterocyclic analogues exist as folded structures. 5, 10-Disubstituted 5, lO- dihydrophosphanthrene systems were first obtained by Davis and Mann in 1964.3 c Although no “ring fluttering” process was cited at that time in the system, the workers ...
