synthesis of 6-nitrocouarrain-3-CO-amino acids and their corresponding methyl esters (II-XVII) and some dipeptide methyl esters (XVIII-XXVI) are described. 6-(N-Tosyl- or N-phthalylaminoacyl)aminocoumarin-3-carboxylic acid methyl esters (XXXIV-XL) and 3-(N-phthalyl- or N-tosylaminoacytyaminocoumarins (XLV-LVI) have been prepared via the carbodiimide and acid chloride methods. Hydrazinolysis of 3- or
描述了6-硝基香豆素-3-CO-氨基酸及其相应的甲酯(II-XVII)和一些二肽甲酯(XVIII-XXVI)的合成。通过碳二亚胺和酸制备了6-(N-甲苯磺酰基-或N-邻苯二甲酰基氨基酰基)氨基香豆素-3-羧酸甲酯(XXXIV-XL)和3-(N-邻苯二甲酰基-或N-甲苯磺酰基氨基乙酰氨基香豆素(XLV-LVI)在四氢呋喃中对3-或6-(N-邻苯二甲酰基氨基酰基)氨基香豆素衍生物进行水合肼解,分别得到相应的3-和6-(氨基酰基)氨基香豆素和羧酸酰肼(XLI-LVIII)。3- (N-甲苯磺酰基-L-Val-L-Leu-)氨基香豆素(LIX)通过叠氮化物法。发现各种取代的3-和6-氨基酰基香豆素衍生物中的二十四种具有对不同微生物的特异性抗菌活性。
