Abstract

The conformational energy and entropy differences of the t-butoxy group were determined using ¹H- and ¹³C-NMR variable temperature techniques and ΔE_conf was calculated by molecular mechanics (MM2). Strikingly small values were observed and discussed in conjunction with the alleviated anomeric effect in 2-t-butoxytetrahydropyran systems.
