The nucleophilic dithiocarbonimidic acid derivatives 2a-e and the isothiourea 2f react with the α-D-glucopyranosyl bromide 1 to yield the corresponding esters 3a-f (cf.Scheme 1). 2a gives with the 3-hexenopyranos-2-ulosyl chloride 4 the ester 5b.Bis(bromomethyl)quinoxaline (8) yields with 2a-c the esters 10a-c (cf.Scheme 2).The reaction of the dipotassium salt 6 with 4 provides di-O-benzoylkojic acid (7), and with 8 the cyclic N-cyanodithiocarbonimidate 9 is obtained.
