The highly enantioselectiveaddition of thioaceticacid to nitroalkenes using a new sulfinyl urea organocatalyst is described. The addition of thioaceticacid proceeds in high yields and enantioselectivities for a variety of aromatic and aliphatic nitroalkene substrates. This new method is useful for preparing chiral 1,2-aminothiol derivatives, as demonstrated by the first enantioselective synthesis

Novel pyridinecarboxamide derivatives of the formula
wherein R is hydrogen, a halogen, a lower alkyl or a lower alkoxy, and the phenyl ring A is a phenyl having a substituent selected from the group consisting of amino, a mono-(lower)alkylamino, a di(lower)alkylamino, or a lower aliphatic acylamino, and a pharmaceutically acceptable salt thereof, and process for the preparation thereof. Said pyridinecarboxamide derivatives have excellent anti-allergic activities even by oral administration and in form of pharmaceutical compositions are useful as an anti-allergic medicine.
式中的新型吡啶甲酰胺衍生物
其中 R 是氢、卤素、低级烷基或低级烷氧基,苯基环 A 是具有选自氨基、一(低级)烷基氨基、二(低级)烷基氨基或低级脂族酰氨基的取代基的苯基,及其药学上可接受的盐,以及其制备工艺。所述吡啶甲酰胺衍生物即使口服也具有极佳的抗过敏活性,以药物组合物的形式用作抗过敏药物非常有用。
