7-Azatryptophan is an unnatural alpha-amino acid with a very potent fl
uorescent activity. It is used as a vehicle for probing the structure
and dynamics of proteins and peptides. Diastereoselective alkylation,
diastereoselective protonation and enzymatic resolution have been test
ed for preparing enantiomerically pure 7-azatryptophan. (C) 1998 Elsev
