- W2951789026 abstract "Protection of functional group is an important and routinely utilized transformation in organic synthesis 1 . In many organic synthetic methods, protection of αhydroxy acids is a necessary process to carry out a multi-step organic synthesis 2 . In these cases, BF3.Et2O has been used for the protection of α-hydroxy acid. However, this procedure has to be carried out using 1.5 equivalent of BF3.Et2O (based on the substrate). Moreover, BF3.Et2O is moisture sensitive, toxic and expensive. A similar process of protection of aldehyde with mandelic acid was reported by Banik using iodine as catalyst 3 . In recent years, iodine has been utilized as an effective catalyst for various protection reactions 4 . As a continuation of the work on iodine catalysed reactions 5 , we describe herein a catalytic method for protection of α-hydroxy acids using molecular iodine (Scheme I). m/z (%)" @default.
