32,170.00 As mentioned above, the yield is further improved when the acetal form thereof, such as dimethyl acetal, is used instead of the aldehyde or ketone in the reaction with L-ascorbic acid. For example, by heating and refluxing a dimethyl acetal of an aldehyde or ketone and approximately equimolar amounts of L-ascorbic acid in an inert solvent such as DMF/hexane in the presence of an acid catalyst such as p-toluenesulfonic acid, Ascorbic acid acetal derivatives can be produced in higher yields than when using aldehydes or ketones. Examples are given below.
