Spectroscopy and Conformational Features

The influence of orbital effects on equilibrium conformation of terminally unsaturated glycenose derivatives has been calculated and compared with results obtained by H coupling constants. Glycenoses and alkenes having the general formula RCH(OR )CH=CHX E) preferentially adopt, in solution, a conformation in which the alkoxy-group eclipses the double bond. This conformation is particularly favoured by resonance when X is an electron- [Pg.187]
