The preparation of a fully differentiated "multiwarhead" siderophore precursor

Murray, Aaron P.,Miller, Marvin J.

, p. 191 - 194 (2007/10/03)

A protected, fully differentiated siderophore analogue has been prepared so that "Trojan Horse"-like siderophore drug conjugates with different drugs can be synthesized. The key steps in the synthesis include controlled preparation of an unsymmetrical urea and its conversion to a fully differentiated isocyanurate by reaction with chloro(carbonyl) isocyanate.
