    Description / Table of Contents: Reactions of Chloromethyl Methyl Ether with Chlorin DerivativesReactions of chloromethyl methyl ether with the methine bridge carbon atom 20 and the 3-vinyl group of chlorin derivatives pyropheophorbide a methyl ester 1, [3-ethyl]-pyropheophorbide a methyl ester (10) and [3-ethyl]-chlorin e6 trimethyl ester (13)〉 are described. The 20-hydroxymethyl group introduced into 13 could be reduced to methyl group with palladium/hydrogen. - The structure of the reaction products are proved by mass- and 1H-NMR spectra.
    Notes: Es werden Reaktionen von Chlormethyl(methyl)ether mit dem Methinbrücken-Kohlenstoffatom 20 und der 3-Vinylgruppe von Chlorin-Derivaten 〈 Pyrophäophorbid-a-methylester (1), [3-Ethyl]-pyrophäophorbid-a-methylester (10) und [3-Ethyl]-chlorin-e6-trimethylester (13)〉 beschrieben. Die in 13 eingeführte 20-Hydroxymethylgruppe konnte mit Palladium/Wasserstoff in eine Methylgruppe umgewandelt werden. - Durch Massen- und 1H-NMR-Spektren werden die Strukturen der Reaktionsprodukte belegt.
