(Z)- and (E)-1,2-di(1-adamantyl)ethene - Marchand, A.P.; Xing, D.; Bott, S.G.; Ogawa, K.; Harada, J. (Elsevier)
A highly stereoselective four-step synthesis of (Z)-1,2-di(1-adamantyl)ethene (1a, overall yield 64%) which employs methyl 1-adamantanecarboxylate (2) as starting material is described. Compound 1a is isomerized quantitatively to the corresponding E- isomer (1b) by reaction with molecular iodine. Some features of the X-ray crystal structures of 1a and 1b are described. | A highly stereoselective four-step synthesis of (Z)-1,2-di-(1-adamantyl)ethene is described.
