3‐Amino‐substituted saturated nitrogen heterocycles are an important subclass of β‐diamines, appearing in a number of clinical agents. Herein, we report a unified approach to these products based upon the regioselective photoredox‐mediated hydroamination of enecarbamates. The amine coupling partner can encompass diverse amine types under a single set of reaction conditions, including primary alkyl

The present invention relates to a novel pyrrolidine compound, which has a potent antagonistic activity against central cannabinoid (CB1) receptor, having the formula [I]: wherein each of R1 and R2 is (A) optionally substituted aryl (or heteroaryl) group, or (B) both of the groups combine to form a group of the formula: one of R3 and R4 is hydrogen and another is hydrogen, hydroxyl, hydroxyalkyl, etc., or both of R3 and R4 combine to form oxo group, R5 is hydrogen or alkyl, Y is single bond, oxygen atom or a group of the formula: -N(R7)-, R6 is optionally substituted hydrocarbon group or optionally substituted cyclic group, R7 is alkyl or alkyloxycarbonylalkyl, provided that R6 is not 4-amino-5-chloro- 2-methoxyphenyl group when Y is single bond and one of the R3 and R4 is hydrogen and another is hydroxymethyl, or a pharmaceutically acceptable salt thereof.
The novel (S)-7-(3-amino-1-pyrrolidinyl)-1-cyclopropyl-6-fluoro-1,4-dihydro-4-oxo-1, 8-n phthyridine-3-carboxylic acid, lower alkyl esters and pharmaceutically acceptable salts thereof are described as well as a method for its manufacture, formulation, and use in treating bacterial infections.
