Demonstrates asymmetric α-regioselective conjugate addition of thiophene derivatives in organic synthesis, indicating new catalytic applications.
The asymmetric α-regioselective conjugate addition of 2-thienylacetones to nitrostyrenes was achieved using a tertiary amine-thiourea organocatalyst, affording the α-addition products in high yields with excellent stereoselectivities. This study provides the first demonstration of an asymmetric α-regioselective conjugate addition of 2-thienylacetones to nitroalkenes.
