A novel one-step synthesis of 3-phenyl-, 4-methyl-3-phenyl- And3-phenyl-4-styrylcoumarins using DCC-DMSO

Hans, Naresh,Singhi, Manasi,Sharma, Vibha,Grover

, p. 1159 - 1162 (2007/10/03)

2-Hydroxybenzaldehydes 1 react with phenylacetic acid and its methoxy derivatives 2 in the presence of DCC in DMSO to afford 3-phenylcoumarins 3. Under identical conditions, 2-hydroxy-acetophenones 4 and 2'-hydroxychalcones 7 give rise to the corresponding 4-methyl-3-phenyl- and 3-phenyl-4-styrylcoumarins 6 and 8, respectively.
