X-RAY STRUCTURE OF A CHIRAL ALKENE: DIRECT EVIDENCE FOR C-H BOND ECLIPSING C=C BOND

Article abstract of DOI:10.1016/S0040-4039(00)77697-0

A single crystal X-ray structure determination of the chiral alkene, (1Z)-1-(benzyloxymethyloxy)-3-cyclohexyl-4-phenyl-1-buten-4-ol, (1), is described.The observed conformation about the C_sp2-C_sp3 bond of 1 is the C-H eclipsed form in the crystal and in solution.The observed torsional angles in the acetal portion of the structure are -65 deg for R'-O-C-O and -59 deg for O-C-O-R''.
