摘要:
A novel process for industrially producing an aromatic nitrile compound represented by the following general formula (3): characterized in that one of an aromatic hydroxymethyl compound, an aromatic alkoxymethyl compound and an aromatic aldehyde compound, all represented by the following general formula (1): or a mixture thereof is reacted with an oxidized bromine compound represented by the general formula (2) MBrOm (2) in the presence of an acid catalyst and either ammonia or an ammonium sat.
摘要:
The present invention provides two basic routes for the total synthesis of taxol having the structure: ##STR1## The present invention also provides the intermediates produced in the above processes, processes for synthesizing these intermediates as well as analogs to taxol. Both the intermediates and analogs to taxol may prove to be valuable anticancer agents.

摘要:
The production of 1,2-dihydroxy-cyclohexadienes from aromatic compounds by a biochemical process by using strains of Pseudomonas putida, and novel 1,2-disubstituted-cyclo-hexadienes are described. Certain of the novel compounds are useful as intermediates in the production of polymers.
摘要:
Novel cyclopentane derivatives which are useful as an intermediate for the preparation of N-(L-aspartyl)-N'-(2,2,5,5-tetramethylcyclopetanecarbonyl)-R-1,1-diaminoethane are represented by the formula (I) ##STR1## wherein R.sub.1 is hydrogen and R.sub.2 is cyano, formyl, carbamoyl, alkanesulfonyloxy, or ##STR2## wherein R.sub.3 and R.sub.4 are the same or different and represent alkyl, substituted alkyl or R.sub.1 and R.sub.2 are combined to be methylsulfinylmethylene, acetoxymethylthiomethylene, halomethylthiomethylene, methylthiomethylene, alkoxymethylene, or --CH.sub.2 --O--.
