Stereochemical study of iminodihydrofurans based on experimental measurements and SOPPA calculations of13C-13C spin-spin coupling constants
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 13C-13C spin-spin coupling constants. The title compounds were shown...
