Über Steroide. 43. Mitteilung. Totalsynthese der racemischen Bisdehydro‐doisynolsäuren. Über oestrogene Carbonsäuren IV

Abstract: 1343 -keit nimmt in der angegebenen Reihenfolge ab. Als Reaktionsprodukte entstehen Ammoniak, Peroxyd und Kohlendioxyd.2. Die oxydative Desaminierung wird durch Hydroxylamin, Semicarbazid und Dimedon gehemmt. Besonders stark wirkt Hydroxylamin, das noch bei einer Konzentration von 0,0001-m. den enzymatischen Vorgang fast vollstandig blockiert. Natriumazid reduziert anfanglich den Sauerstoffverbrauch, beeinflusst aber nur wenig die Desaminierung.3. Die Fahigkeit der Oxydation von Polyaminen nimmt mit zunehmende… Show more

“…However, treatment with KOH at 160−170 o C led to complete cleavage of the (−)-menthyl or (−)-8-phenylmenthyl group to form 2 and 3 and some additional cleavage of the 6-methoxy group to form 4 and 5 (Scheme 4). 25 If heating were provided for a longer period, complete conversion to 4 and 5 could be achieved. This method can also be used to prepare compounds having other substituents on the naphthalene ring or the carboxylic acid side chain.…”

“…In a brilliant series of papers [86][87][88][89][90][91][92][93][94] they also described the total synthesis of this compound (Scheme 3-11). The keto ester 15, an intermediate in Bachmann's synthesis of equilenin (Scheme 3-2), was treated with ethylmagnesium bromide to form the hydroxy ester 117.…”

“…By reacting ethylmagnesium bromide with XV and dehydrating the resulting tertiary carbinol the ethylidene derivative (XVI) was obtained. After reduction of the double bond and demethylation of the ester and the ether groups there resulted a mixture of the two racemic bisdehydrodoisynolic acids XVIIa and ß (13).…”
