REGIOSELECTIVE ACYLATIVE CLEAVAGE OF CYCLIC FORMAL OF CHLORAMPHENICOL

The amide 6 has been synthesised by reacting the amine 3 with dichloroketene in situ.This amide 6 on nitration gave formal 7, which when reacted with acetic anhydride and p-toluene sulfonic acid underwent regioselective cleavage of the dioxane ring to furnish the hemiacetal 11.This on treatment with methanol-water-ammonia yielded chloramphenicol 2.
