O-Isopropylidene derivatives of sugars are readily prepared by using the Lewis acid and dehydrating agent triphenylphosphine polymer-bound/I2 complex. This new method is characterized by smooth, non-equilibrating reaction conditions and a very clean, simple work-up, making it particularly suitable for O-isopropylidenation of sugars under mild conditions and with low environmental impact.

Abstract
O-Isopropylidene derivatives of sugars are readily prepared by using the Lewis acid and dehydrating agent triphenylphosphine polymer-bound/I2 complex. This new method is characterized by smooth, non-equilibrating reaction conditions and a very clean, simple work-up, making it particularly suitable for O-isopropylidenation of sugars under mild conditions and with low environmental impact.File in questo prodotto:
