A new Route to the Synthesis of Pyrazines and Oxazoles
Abstract
Decaboxylative   transamination of the   α-amino  acids glycine, alanine   and   tyrosine    in the presence of  the  symmetrical   and a symmetrical  benzoins ; [4 -N- di Methyl amino benzoin ] , [4,ˉ4 – di  chloro benzoin ] ,[4– hydroxy benzoin] , [4 -chloro benzoin ] , [ 3,ˉ3-  di bromo benzoin ] and [ 2-  nitro  benzoin ]. This  has  led  to  the  formation of oxazoles , tetra substituted pyrazine and the corres ponding benzilsDownloads
