Intramolecular OH π hydrogen bonding in 6- and 7-hydroxy-5,6,7,8-tetrahydro-5,8-methanoisoquinolines and their N-oxides

Abstract

I.r. spectral measurements gave the frequency shift and integrated intensity of the hydroxy stretching band for the title compounds in dilute solutions of carbon tetrachloride and chloroform. Intramolecular OH π hydrogen bondings with characteristic differences were found.
