A method for the anal. of the optical purity of a series of chiral substituted tetrahydroisoquinolines (THIQs) was developed. The method is based on pre-column derivatization of the analytes with the derivatization reagent (-)-(1R)-menthyl chloroformate. The derivatization reaction selectively gives diastereomeric carbamates that are resolvable on an achiral non-polar GC column. The developed technique covers variously substituted THIQs, which differ significantly in volatility, steric and electronic properties. In all cases, the resolution factors (R) exceeded the value of 1.5. The method represents a robust way of anal. of mixtures of THIQs, which are often present in various matrixes such as body fluids, tissues and reaction mixtures The experimental process involved the reaction of (1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl carbonochloridate(cas: 14602-86-9).Quality Control of (1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl carbonochloridate

Chen, Mao; Buchwald, Stephen L. published an article in 2013, the title of the article was Continuous-flow synthesis of 1-substituted benzotriazoles from chloronitrobenzenes and amines in a C-N bond formation/hydrogenation/diazotization/cyclization sequence.Product Details of 38939-88-7 And the article contains the following content:

We have developed an efficient and regiospecific synthesis of 1-substituted benzotriazoles from chloronitrobenzenes and amines by a C-N bond formation/hydrogenation/diazotization/cyclization sequence under continuous-flow conditions. Two approaches beginning either with an SnAr reaction or Pd catalysis were developed to prepare unsym. substituted benzotriazoles with a range of substituents. Of particular note is that benzotriazoles that bear various N-substituted groups, including alkyl, aryl, and heteroaryl, can all be efficiently and regiospecifically accessed with the described method. This protocol represents a successful example of a continuous-flow method with consecutive multiphase processes. The experimental process involved the reaction of 2-Chloro-4-methyl-1-nitrobenzene(cas: 38939-88-7).Product Details of 38939-88-7
