P. Scrimin et al., A ZINC(II)-ORGANIZED MOLECULAR RECEPTOR AS A CATALYST FOR THE CLEAVAGE OF AMINO-ACID ESTERS, Journal of the Chemical Society, Chemical Communications, (11), 1995, pp. 1163-1164
The Zn-II complex of ligand 1a, a derivative of TREN bearing three 3-h
ydroxyphenyl units at the amines of its arms, acts as a transacylation
catalyst of the p-nitrophenyl ester of 4-pyridinecarboxylic acid.
