✦ Synopsis

In previous communications, we reported that the acetonation of L-sorbose (I) with acetone dialkyl ketals afforded IIa-VIIa (1,2) by a different mode than the acetonatlon with acetar.:, (3). We have since investigated the reaction mechanisms of the former acetonation and concluded that the reaction proceeds through intermediate keto-forms as shown in Chart .

## Abstract Despite the fact that L‐sorbose has been widely used for the synthesis of vitamin C at an industrial level, its use in organic synthesis remains rare. However, a survey of the chemical literature shows that this unusual sugar can be transformed into interesting derivatives.
