Abstract

Abstract Heterocyclic compounds of four 6-phenyl-5, 6, 7, 8-tetrahydro-4H-1, 3, 6- dioxazocines have been synthesized by condensation of the corresponding N, N-bis (2- hydroxyethyl)-or N, N-bis (2-hydroxypropyl) anilines with aldehyde or ketone in the presence of acid. The pmr and cmr spectra of these compounds were recorded to determine their stereochemical structures. On the basis of the chemical shifts due to the γ-effects, the ...
