| Abstract: | A sequential one-pot
two-step tandem reaction for an efficient synthesis of 2,3-dihydrofurans
substituted with 2H-benzopyrans has
been developed. One-pot reaction of in
situ formed benzopyran substituted pyridinium ylides with aromatic
aldehydes and dimedone gives corresponding 2,3-dihydrofurans in good yields. The
structures of the final compounds have been assigned as trans-2,3-dihydrofurans on the basis of their NMR spectra. |
