N,N′-[(8-endo,11-endo-Dihydroxypentacyclo[5.4.0.02,6.03,10.05,9]undecane-8,11-diyl)bis(methylenecarbonyl)]di-l-phenylalanine
Abstract
The title compound, C33H36N2O8, is the first example of a disubstituted peptidic pentacycloundecane (PCU) diol. The structure displays an array of inter- and intramolecular hydrogen bonding by both amide and alcohol functional groups. This hydrogen-bonding system connects the molecules into a three-dimensional network.
