Synthesis of Bis(Carbamoyl Ester) Derivatives of D-Glucose as Antifungal Products
摘要:
Regiospecific carbamoylation of di-O-isopropylidene protected D-glucose gave a series of carbamoyl, thiocarbamoyl and dithiocarbamoyl esters at the C-3 secondary site. These were partially and fully deprotected to give two series of derivatives such that a choice of the extent of hydrophilic character could be made. The partially protected products were further derivatized regioselectively with a second carbamoyl, thiocarbamoyl or dithiocarbamoyl group at the C-6 primary site. We also report on antifungal properties of some of those compounds.

unprotected carbohydrates possess both modulable hydrophilic character and potential biological properties. Some carbamoyl esters showed, by NMR spectroscopy, characteristics of Z-E isomerism; the rotational energy barrier was higher for the thiocarbamates than for the corresponding carbamates.
