Trityl-Directed Regiospecific Synthesis of 2,3-Disubstituted Bioimidazoles
摘要:
We report an efficient trityl-directed regiospecific synthesis of 2,3-disubstituted-L-histdines and 2,3-disubstituted histamines starting from alpha-N-trifluoroacetyl-L-histidine methyl ester and alpha-N-trifluoro-acetylhistamine respectively in five steps.
