Empress Wuyuan. Emperor Hui of Jin ( simplified Chinese: 晋惠帝; traditional Chinese: 晉惠帝; pinyin: Jìn Huì Dì; Wade–Giles: Chin Hui-ti; 259 – January 8, 307 [2] ), personal name Sima Zhong (司馬衷), courtesy name Zhengdu (正度), was the second emperor of the Jin dynasty (266–420). Emperor Hui was a developmentally ...
15. Sept. 2010 · The Erlenmeyer–Plöchl azlactone synthesis is the preparation of azlactones (also called oxazolones) in a Z configuration (originally assigned to the E configuration) by condensation of aromatic aldehydes with hippuric acid (the benzoyl glycine derivatives) in the presence of acetic anhydride. The azlactones are useful for the synthesis of α-ketos, a-amino acids and peptides. The ...

7. Aug. 2006 · The classical Erlenmeyer azlactone synthesis (1893) is an important method for preparing aromatic α-amino acids, 1 and azlactones continue to find diverse applications in synthesis as revealed by several recent reports. 2, 3, 4 These include asymmetric syntheses of various natural and unnatural amino acids 2, 3 and peptide synthesis. 4 The general revival of azlactone chemistry is exemplified ...

The Bergmann azlactone peptide synthesis is a classic organic synthesis process for the preparation of dipeptides . In the presence of a base, peptides are formed. s of N-carboxyanhydrides of amino acids with amino acid esters ( 1 ). [1] This reaction can be looked at in further detail by Bailey. [3]
