Four sulfonyl amines that is O-( In summary, the mild condition, high yields of products, operational simplicity, easy availability of reagent and no external use of explosive hydrogen gas makes this methodology a more useful and practical alternative to the existing methods for reduction of ,-unsaturated carbonyl compounds. This extends the synthetic application to O-mesityl(sulfonyl)hydroxylamine. We believe that this method will find useful applications in the field of organic synthesis.
