The synthetic condition of tulobuterol was optimized to gain lower impurity content. Two intermediates were analyzed, and three degradation impurities were isolated using preparative liquid chromatography for the first time and subsequently characterized by various techniques. Possible degradation impurities were...

A reliable synthetic protocol toward a series of fused chalcogenophenobenzochalcogenophene (CBC) building blocks was developed based on a Fiesselmann reaction. The obtained CBC units were applied in McMurry and Stille coupling reactions toward symmetric regioisomeric ene-linked dimers. These π-conjugated compounds...

2-Chloroacetophenone (CN) and o-chlorobenzylidene malononitrile (CS) are the most common chemical agents used as lacrimators in the United States. There is a lack of complete spectral data on these compounds in the literature. Spectral data (ultraviolet, fluorescence, proton nuclear magnetic...

(R)-chlorprenaline, a selective activator of beta2 receptor and an effective drug for bronchitis and asthma, is industrially prepared from (R)-2'-chloro-1-phenyl-ethanol. In this communication, we describe (1) the identification of Saccharomyces cerevisiae B5 as an effective host for stereoselective reduction of...
