    摘要: Improved procedures and intermediates for synthesizing 11-deoxyprostaglandins wherein trans-2,3-dicarbomethoxycyclopentanone is prepared by the novel kinetically-controlled cyclization of 1,2,4-tricarbomethoxybutane using a dispersion of sodium hydride in dry p-xylene. Selective alcoholysis of the 2-position carbomethoxy group with benzyl alcohol, followed by alkylation allows for a wide range of upper side chains to be introduced at the 2-position of the cyclopentanone ring. The unwanted carbobenzyloxy group at the 2-position can then be removed easily by controlled hydrogenolysis followed by decarboxylation. This procedure allows for simultaneous epimerization of the 2-position side chain to the desired trans-configuration, relative to the carbomethoxy group in the 3-position, as well as for reduction of the 2-hexynyl moiety of the side chain to the desired cis-olefinic group of the E.sub.2 -type 11-deoxyprostaglandins, or through total reduction to the alkane upper side chain of E.sub.1 -type prostaglandin analogs. Modification thereafter of the carbonyl group at the 3-position of the cyclopentanone ring by a variety of reagents allows introduction of the lower side chain present in the prostaglandins themselves or a variety of other side chains derived from the 3-carboxy-, 3-hydroxymethyl- or 3-aldehyde-substituted cyclopentanone ring. From the latter, 11-deoxyprostaglandins can be prepared by known procedures.

    摘要: Cyclization of a dialkali metal salt of 1,1,2,3-4,4-hexacyano-2butenediide with acid yeilds 1-amino-2,3-4,5,5pentacyanocyclopentadiene which is converted to 1-amino-2,34,5,5-tetracyanocyclopentadiene which is converted to 1-amino2,3,4,5-tetracyanocyclopentadiene with strong mineral acid. Reaction of the pentacyanocyclopentadiene with nitrous acid gives 1-diaza-2,3,4,5-tetracyanocyclopentadiene which can be reacted with trialkyl or triaryl phosphorus to give 1-tri(aryl or alkyl)phosphazino-2,3,4,5-tetracyanocyclopentadiene. The diazotetracyanocyclopentadiene compound can be reacted with alkali metal compounds preferably under reducing condition to yield salts wherein the diazo group is replaced with hydrogen, amino, cyano, hydroxy, carboxy, alkoxycarbonyl, alkyl, aryl, phydroxyphenyl, nitro and mercapto groups. The cyanocyclopentadiene compounds are useful as rodenticides and as rocket propellants.
