Five-step syntheses of dimethyl tricyclo[3.3.0.03,7]octane-1,5-dicarboxylate (13) and its 3,7-dimethyl derivative 14 from the readily available cis-bicyclo[3.3.0]octane-3,7-diones 1 and 2, respectively, are described. The key-step implies the iodine oxidation of the bis-enolate derived from the corresponding dimethyl cis-bicyclo-[3.3.0]octane-3,7-dicarboxylates 11 and 12, thus being developed a new synthetic entry into the tricyclo[3.3.0.03,7]octane skeleton. Also, some attempts to synthesize diester 13 by using known methodology for the synthesis of compounds containing this tricyclic skeleton are described. Eine kurze Synthese von Tricyclo [3.3.0.03,7]octan-1,5-dicarbonsaure-dimethylester und seines 3,7-Dimethylderivats. Ein neuer Weg zum Tricyclo [3.3.0.03,7]octan-Gerust Die 5-stufige Synthese von Tricyclo[3.3.0.03,7]octan-1,5-dicarbonsaure-dimethylester (13) und seines 3,7-Dimethylderivats 14 ausgehend von den leicht zuganglichen cis-Bicyclo[3.3.0]octan-3,7-dionen 1 bzw. 2 wird beschrieben. Schlusselreaktion ist die Oxidation der Bis-enolate der cis-Bicyclo[3.3.0]octan-3,7-dicarbonsaure-dimethylester 11 und 12 mit Iod zum Tricyclo-[3.3.0.03,7]octan-Derivat 13 bzw. 14. Zusatzlich wird die Synthese des Diesters 13 nach bekannten Methoden versucht.
