Preparation of 3,4,5-substituted furan-2(5H)-ones using aluminum hydrogen sulfate as an efficient catalyst

Various derivatives of 3,4,5-substituted furan-2(5H)-ones have been readily prepared by using aluminum hydrogen sulfate [Al(HSO4)3] as an efficient catalyst in good yields and milder reaction conditions. The versatility of this protocol has been demonstrated with various substituted furan-2(5H)-ones.
