Abstract

Configurational assignment and conformational analysis of a series of iminodihydrofurans obtained from cyanoacetylenic alcohols were performed on the basis of experimental measurements and high‐level ab initio calculations of their ^13^C^13^C spin–spin coupling constants. The title compounds were shown to form and exist in solution as the individual Z isomers, adopting the orthogonal orientation of the amino, alkylamino and dialkylamino groups and the s‐trans orientation of the CONH~2~ group at the C^4^ position of the 2,5‐dihydro‐2‐iminofuran moiety.

A series of 23 bridgehead-substituted bicyclo[l.l.l]pentanes were synthesized and the 3J(Cl-H) coupling constants determined from their proton-coupled I3C NMR spectra. It was found that the values of the couplings are strongly dependent upon the type of substituent present, with powerful effects exe
