The new helical compounds 1–3 have been synthesized. 1 and 2 are separated into the enantiomers by chromatography on cellulose triacetate. The rotatory powers are high: e.g., [α]math image = 2096 for 1. The racemization/ring inversion barriers range between 115 and 125 kJ/mol. X-ray analyses of 1–3 reveal different torsional angles between the rings ABC from 3.6 to 10.4°. They are compensated ...
