Synthese des Desoxo‐phyllerythrins, der Grundsubstanz des Chlorophylls

Chlorophyll.

“…this behavior can only be explained by an ethanone bridge between C3 The constitution of desoxophylloerythrin and of phylloerythrin, however, could also be demonstrated by synthesis (37,39,40,16). On the basis of elementary analysis only the formula of a monocarboxylic acid (page 43) or the ring formula (XVI) with two less hydrogen atoms, stood available for desoxophylloerythrin.…”

“…The synthesis was carried out according to the following scheme, and gave a substance which proved to be identical with the "natural product" in all its properties (38). Desoxophyllerythrin gave, on oxidation with We admit that the position of the CO group at 9 in phylloerythrin is not proved by this synthesis.…”
