Oxy ring-functionalized cyanoarylacrylates, R 1 PhCH = C(CN)CO2R 2 have found various applications as functional compounds in organic and polymer synthesis. Thus, phenoxy ring-substituted ethyl cyanoarylacrylate (ECAA) was used in synthesis of tetrazoles compounds ; it was a product of condensations catalyzed by triazine-based microporous network , imidazolium chloride immobilized SBA-15 , and biocatalyst lipase, Aspergillus oryzae . The ECAA was also used in N,N'-dioxide-lanthanum(III)catalyzed asymmetric cyclopropanation with 2-bromomalonates . It was employed in DBU-mediated annulations of donor-acceptor cyclopropanes , in synergistic NaBH4 reduction/cyclization in synthesis of 3-oxabicyclo[3.1.0]hexane derivatives , as well as in studies on synthetic access to pyrano quinoline and 3-substituted quinoline derivatives . Benzyloxy ring-substituted ECAA was used in synthesis and biological evaluation of arylidene-thiazolidinediones with potential hypoglycemic and hypolipidemic activities . Acetyl ring-substituted ECAA was involved in synthesis from nitriles with retention of the cyano group , in iridium hydride complex catalyzed addition of nitriles to carbon-nitrogen triple bonds of nitriles , and in synthesis (E)-trisubstituted alkenes via bismuth triflate-catalyzed rearrangement of acetates .
