The conformational analysis of saturated heterocycles. Part XXXI. 1-t-Butylpiperidine-4-spiro-4′-(1′,3′-dioxolan) and 1,3-dioxan-5-spiro-4′-(1′,3′-dioxolan)
Abstract
The use of dipole moment and n.m.r. measurements of spiro-1-t-butylpiperidines and spiro-1,3-dioxans is proposed as a general method for the investigation of intramolecular interaction in situations of defined geometry. The method is applied to the title compounds.
