MASS SPECTROMETRY OF STILBENES. PART II. NEW ETHERAL DERIVATIVES OF (E)-STILBENOL-4 AND (E)-STILBENDIOL-4,4'
Wyrzykiewicz, Elzbieta,Sylwestrzak, Urszula
, p. 951 - 962 (2007/10/02)
High resolution mass spectra of twelve new (E)-4-carboxyalkoxy (or alkoxycarbonylalkoxy) and (E)-4,4'-dicarboxyalkoxy (or dialkoxycarbonylalkoxy) substituted derivatives of (E)-stilbenol-4 and (E)-stilbendiol-4,4' were studied.
