3-O and 2-C Alkylation of L-ascorbates with benzyl halides and N-substituted indolemethanol derivatives

Korolev,Luzikov,Reznikova,Preobrazhenskaya

, p. 457 - 462 (2010)

Coupling of alkali metal ascorbates with benzyl halides and 2and 3-hydroxymethylindole methanesulfonates resulted in L-ascorbic acid 3-Oand 2-C-derivatives. In contrast to 3-Obenzyl L-ascorbate, its indole analogs are unstable compounds, which underwent decomposition or rearrangement during isolation to give thermodynamically stable 2-C-isomers.
