01 - 246Synthesis and Receptor Binding Affinity of Conformationally Re-stricted Retinoic Acid Analogues. — Efforts to synthesize twoconformationally restricted retinoids utilizing a cyclopropyl ring as bioisosterefor the C9–C10 double bond are described. The attempted synthesis of the cis-isomer leads mainly to unidentified products and the unexpected epimerizationto the trans-derivative (VII). The latter is synthesized independently startingfrom the cyclopropane (I). — (WONG, M. F.; REPA, J. J.; CLAGETT-DAME, M.; CURLEY, R. W. JUN.; Bioorg. Med. Chem. Lett. 7 (1997) 17,2313-2318; Div. Med.
