    Description / Table of Contents: Synthesis and Behaviour of 1.5-Didehydronorhygrine and 1.6-DidehydroisopelletierineThe title compounds (5, 6) are hypothetical intermediates in the biosynthesis to mono- and bicyclic pyrrolidine and piperidine alkaloids. A chemical synthesis closely following a biochemical pathway discussed by several authors is described.
    Notes: Die beiden Titelverbindungen (5, 6) stellen mögliche Zwischenstufen in der Biosynthesekette mono- und bicyclischer Pyrrolidin- bzw. Piperidinalkaloide dar. Es wird über eine chemische Synthese berichtet, die sich eng an einen von mehreren Autoren diskutierten Biosyntheseweg anschließt.

    Description / Table of Contents: Preparation and Behaviour of 1.5-Didehydrohygrine and N-Methyl-1.6-didehydroisopelletierineA one step synthesis of the title compounds and their cyclisation to tropinone and pseudopelletierine is reported. A second synthesis of 1.5-didehydrohygrine (5) involving 1-Methyl-Δ1-pyrrolinium-5-carboxylic acid (19) is described.
    Notes: Es wird über eine einstufige Synthese der als Alkaloidvorstufen diskutierten Titelverbindungen berichtet und ihre Cyclisierung zu Tropinon und Pseudopelletierin nachgewiesen. Ferner wird eine über die 1-Methyl-Δ1-pyrrolinium-carbonsäure-(5) (19) führende, mehrstufige Synthese von 1.5-Didehydro-hygrin (5) beschrieben.
