Research on furan acetal compounds - VII. PMR spectra, configuration, and conformations of substituted 2-(α-furyl)-1,3-diozanes

Abstract

The configuration and preferred conformations of a number of stereoisomeric 2-(α-furyl) 1,3-dioxanes were established by PMR spectroscopy. It is shown that cis orientation of the NO2 groups with respect to the furyl ring is primarily realized for 2-(α'-nitro-α-furyl)-5-ethyl-5-nitro-1,3-dioxanes. © 1975 Plenum Publishing Corporation.
