摘要:
A novel method has been found to produce 2,2′-anhydro-1-(β-L-arabinofuranosyl)thymine as a novel useful intermediate compound. A novel method has been further found to produce thymidine from 2,2′-anhydro-1-(β-L-arabinofuranosyl)thymine. A novel method has been further found to L-2′-deoxyribose derivatives as a useful synthetic intermediate through L-2,2′-anhydro-5,6-dihydrocyclouridine derivative. According to these methods, synthesis of various L-nucleic acid derivatives, synthesis of which has been difficult till now.
摘要:
In the case that a selectively monoacylated phenylenediamine derivative which is useful as any of medicines, agricultural chemicals, animal drugs and the intermediates of chemicals is prepared by reacting a benzoic acid derivative with a phenylenediamine derivative, the benzoic acid derivative is converted into a benzoyl imidazole derivative and this benzoyl imidazole derivative is then reaction with the phenylenediamine derivative, whereby the improvement of a preparation efficiency and the high selectivity of the monoacylation can be achieved, the steps of protection and deprotection being omitted.
摘要:
A glycide derivative represented by the following general formula (I) is produced by reacting a hydroxyaryl or heteroaryl represented by A-OH with glycidyl tosylate in the presence of a cesium base as a base. Thereby, an aryl glycidyl ether derivative, which is an important intermediate for drug production, can be produced easily and reliably. Particularly when optically active glycidyl tosylate is used, said compound can be obtained at a high optical purity. ##STR1## wherein A represents an aryl group or a heteroaryl group.
摘要:
Novel heterocyclic compounds, which are represented by the following general formula, useful as anticancer drug potentiaters having a potentiating effect on the incorporation of anticancer drugs into cancer cells, the compounds each synthesized by, for example, reacting a epoxy compound obtained by reacting a heterocyclic compound with an epihalogenohydrin, with an amine derivative.
