Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels. 497-23-4, Name is Furan-2(5H)-one, molecular formula is C4H4O2. In an article, author is Yan, Juzhang,once mentioned of 497-23-4, Name: Furan-2(5H)-one.
Organocatalytic 1,4-Addition of Azadienes with 3-Homoacyl Coumarins toward Highly Enantioenriched Benzofuran Coumarin Skeletons
A highly enantioselective 1,4-addition reaction of azadiene with 3-homoacyl coumarin has been accomplished by low amounts of bifunctional cinchona alkaloid catalysis under mild conditions. Varieties of benzofuran coumarin skeletons were obtained in moderate to high yields (up to 99%) with excellent enantioselectivities (up to 99% ee) and complete diastereoselectivity.
