Systematic Evaluation of 2-Arylazocarboxylates and 2-Arylazocarboxamides as Mitsunobu Reagents

2-Arylazocarboxylate and 2-arylazocarboxamide derivatives can serve as replacements of typical Mitsunobu reagents such as diethyl azodicarboxylate. A systematic investigation of the reactivity and physical properties of those azo compounds has revealed that they have an excellent ability as Mitsunobu reagents. These reagents show similar or superior reactivity as compared to the known azo reagents and are applicable to the broad scope of substrates. pKa and steric effects of substrates have been investigated, and the limitation of the Mitsunobu reaction can be overcome by choosing suitable reagents from the library of 2-arylazocarboxylate and 2-aryl azocarboxamide derivatives. Convenient recovery of azo reagents is available by one-pot iron-catalyzed aerobic oxidation, for example. SC-DSC analysis of representative 2-arylazocarboxylate and 2-arylazocarboxamide derivatives has shown high thermal stability, indicating that these azo reagents possess lower chemical hazard compared with typical azo reagents.

A PROCESS FOR OPTICAL PURE (R)-2-PHENOXYPROPIONIC ACID DERIVATIVES

The present invention relates to a method for manufacturing optically active (R)-2-phenoxypropionic acid derivatives. More particularly, the present invention relates to a method for manufacturing optically active (R)-2-phenoxypropionic acid derivatives with high purity by using p-substituted phenol derivatives and alkyl (S)-2-arylsulfonyloxypropionate as starting materials and reacting them at 60 to 100 °C in the presence of an alkalimetal salt as a base and. a hydrocarbon solvent.

PROCESS FOR PREPARING (R)-ARYLOXYPROPIONIC ACID ESTER DERIVATIVES
