标题:Total syntheses of selenoneine, iso-selenoneine, and isomers
发明人：ACHOUBA ADEL; AYOTTE PIERRE
权利人:UNIV LAVAL
摘要:A process for the total synthesis of selenoneine, iso-selenoneine, and isomers thereof is disclosed herein. Regarding the synthesis of selenoneine, the process comprises reacting an alkylated L-histidine methyl ester with a stable, acid-labile alkylating agent followed by reaction with elemental selenium under mildly basic conditions; and an acidic hydrolysis step. Regarding the synthesis of iso-selenoneine, the process comprises reacting hercynine with an electrophilic R—Se—X species, wherein the R—Se—X species is obtained by reaction of an alkyl diselenide with X 2 , and wherein X is F, Cl, Br or I; and a deprotection reaction.
