Planar chiral oxa-[7]orthocyclophene 1a was designed and synthesized with two different synthetic routes. X-ray crystallographic analyses of 1a and its platinum complex revealed a highly distorted ring structure and the absolute stereochemistry of 1a, respectively. Epoxidation and [2,3]-Wittig rearrangement of 1a provided with central chiral molecules, without the loss of enantiomeric purity.
