Abstract
A series of new 2‐methylthio‐7‐(p‐R‐phenyl)‐8‐phenoxy‐4,5‐benzo‐3‐aza‐2‐nonem, IIIa, have been synthesized by regiospecific cycloaddition of phenoxyacetyl on to 2‐methylthio‐4‐(p‐R‐phenyl)‐3H‐1,5‐benzodiazepines IV. The structure was established by ir, 1H‐nmr and ms spectral data together with 13C‐nmr spectral data of desulfurization products, VIa. Likewise, a study has been made of the fragmentation upon electron impact of IIIa and IV. All the spectra analyzed contain molecular ions and the principal fragmentation routes takes place either from the molecular ion or from m/e (M+ — 134) ion. This ion is the base peak for all the compounds analyzed.This publication has 12 references indexed in Scilit:
