category: oxazolidine, Researchers are common within chemical engineering and are often tasked with creating and developing new chemical techniques, frequently combining other advanced and emerging scientific areas. In a article, 139009-66-8, molcular formula is C11H19NO5, introducing its new discovery.
A method for the synthesis of beta3-amino acids starting from alpha-amino acids is described. This conversion can be effected by an eight-step procedure which involves the transformation of the carboxylic group into an alkyne followed by a selenium-mediated conversion of the carbon-carbon triple bond to a Se-phenyl selenocarboxylate intermediate. The reactive Se-phenyl selenocarboxylate intermediates can be trapped with water, alcohols or the amine of an amino acid derivative to give beta3-amino acids, beta3-amino esters or mixed peptides, respectively. The whole transformations of the carboxylic group into an alkyne and of the alkyne group into beta3-amino acids may not require purification of the intermediate products but a work-up and isolation procedure of crude materials.
This is the end of this tutorial post, and I hope it has helped your research about 139009-66-8
