different route than previously used, from ethyl aminomalonate hydrochloride. Trial asymmetric syntheses were unsuccessful for papain catalysis of such achiral amides with aniline. A few organic solutes were tested for their effects on the activity of papain during anilide synthesis. The pH dependence of yield was studied for papain catalysis of reactions between aniline and hippuric amide and then
通过木瓜蛋白酶催化与苯胺,三种茴香胺,三种氨基酚和三种氟苯胺的反应已实现了Z-dl-丙氨酸酰胺的拆分。所得的大多数酸酐显示出优于外消旋酰胺的95%分离度。在过量的干燥甲醇存在下,借助于最近报道的催化脱水器,制备了马尿酸,z-甘氨酸,zl-丙氨酸和z-dl-丙氨酸的四种甲酯。随后用氨处理产生酰胺。用与以前所用不同的方法,从氨基丙二酸乙酯盐酸盐合成了三种N-酰基氨基丙二酸酰胺。试验性不对称合成未能成功地用木瓜蛋白酶催化此类非手性酰胺与苯胺的反应。测试了一些有机溶质对苯胺合成过程中木瓜蛋白酶活性的影响。
