~1H, ~(13)C and ~(17)O NMR spectral strudies on monocyclic dioxolanes, dioxanes, dioxeanes and dioxocanes and cycloalkane-fused (5-8-membered) bicyclic 1, 3-dioxolanes and 1, 3-dioxanes

摘要

~1H, ~(13)C and ~(17)O NMR data for a set monocycilc dioxolanes, dioxlanes, dioxanes, dioxepanes, and dioxocanes and cycloalkane-fused (5-8-membered) bicyclic 1, 3-dioxolanes and 1, 3-dioxanes comprising 81 compounds in all are presented. This systematic configurational and conformational study addresses the deficiency in the available data regarding the conformational behavior and, in particular, the scant ~(17)O NMR data for 1, 3-dioxaalkanes. Many of the compounds are new and together with the known compounds measured under similar conditions they constitue a well documented compilation of spectral data suitable for addition to databases and assistance in chemical shift calculations.
