Description / Table of Contents:
Chemical ionization mass spectrometry of the title compounds demonstrates that the formation of the [M+H—CH3OH]+ ions is strongly influenced by the degree as well as the type of alkyl substitution of the α-carbon atom. The extent of cyclization (i.e. formation of [M+H—CH3OH]+) closely resembles that of the activated esters in condensed phases.
Notes:
Art und Anzahl der Alkylsubstituenten am α-C-Atom der Titelverbindungen beeinflußen in entscheidender Weise die durch chemische Ionisation induzierte Methanol-Eliminierung aus den [M + H]+-Ionen. Die Cyclisierungstendenz entspricht sehr stark der von aktivierten Estern in kondensierter Phase.
