Sulfonated graphene (GR-SO₃H) has emerged as a mild, efficient and sustainable catalyst for the preparation of O-isopropylidene derivatives of unprotected and anomeric-protected carbohydrates with acetone and 2,2-dimethoxypropane at room temperature. This methodology not only provides excellent yields but also reduces reaction times, and it demonstrates exceptional recyclability, allowing the catalyst to be reused multiple times.
