标 题 :Method for the synthesis of pyrrole and imidazole carboxamides on a solid support
发明人：DERVAN PETER B; BAIRD ELDON
权利人:CALIFORNIA INST OF TECHN
摘要:The present invention describes a novel method for the solid phase synthesis of polyamides containing imidazole and pyrrole carboxamides. The polyamides are prepared on a solid support from aromatic carboxylic acids and aromatic amines with high stepwise coupling yields (>99%), providing milligram quantities of highly pure polyamides. The present invention also describes the synthesis of analogs of the natural products Netropsin and Distamycin A, two antiviral antibiotics. The present invention also describes a novel method for the solid phase synthesis of imidazole and pyrrole carboxamide polyamide-oligonucleotide conjugates. This methodology will greatly increase both the complexity and quantity of minor-groove binding polyamides and minor-groove binding polyamide-oligonucleotide conjugates which can be synthesized and tested.

标题:Enzyme-catalytic method for the direct stereoselective synthesis of gamma-(acyloxy) carboxylic acids

摘要:The present invention is a method for the stereoselective straightforward synthesis of gamma-acyloxy carboxylic acids of novel structure starting from racemic gamma-hydroxy carboxylic acid salts that are obtained by alkaline hydrolysis of the racemic gamma-lactones. The salt is acylated by enzyme catalysis in an organic solvent containing an acyl donor and an immobilised lipase, on stirring at room temperature (ca 20 °C) until reaching the conversion rate required. After that, the reaction mixture is acidified and extracted and the product treated with catalytic amount of para-toluenesulfonic acid in toluene during the time required for the relactonisation of the unreacted salt enantiomer. Thereafter, the target gamma-acyloxy carboxylic acid formed from one enantiomer of the starting compound and relactonised gamma-lactone formed from the other, unreacted enantiomer of the starting compound are isolated using a routine separation method, such as distillation, extraction with NaHCO3 water solution followed by acidification or column chromatography.
