If you could tell me which ester was produced, that'd be great!
none whatsoever: ascorbic acid is
not a carbonic acid, and hence will form no esters (except that ascorbic acid already is an ester in its own right)
maybe you might achieve some trans-esterification instead, but I doubt that , as the usual reactions of ascorbic acid are more complex and counter-intuitive than that
an overview of the chemistry of ascorbic acid you'll find
