Description and Uses

3-Butenoic acid was used in the synthesis of polyethylene glycolated boltorn coatings. It was used to study the inhibition of the enzyme-catalysed conversion of D-tyrosyl- phenylalanyl-glycine to D-tyrosyl-phenylaline amide by non-peptide carboxylic acids. It was used in preparation of strained nitroso Diels-Aldrer adducts which undergo a domino ROC metathesis in the presence of Ru-carbene catalysts and olefins.
