摘要
A convenient and efficient method for the synthesis of furoxan derivatives from alpha-nitro-ketoximes and sulfonyl chlorides is reported. A wide variety of furoxan derivatives were smoothly obtained in good yields via a DABCO-mediated cascade sulfonylation/cyclization process under mild conditions. The usefulness of this method was also demonstrated by the conversions of the furoxan products into other promising compounds. (C) 2015 Elsevier Ltd. All rights reserved.
