V. Nair et al., PERISELECTIVE [4-PI-PI] CYCLOADDITION REACTIONS OF 3-ETHOXY CARBONYL-2H-CYCLOHEPTA[B]FURAN-2-ONE WITH ARALKENES(2), Chemistry Letters, (6), 1997, pp. 505-506
The periselective [4 pi+2 pi] cycloaddition reactions of 3-ethoxy carb
onyl-2H-cyclohepta[b]furan-2-one with different aralkenes is described
. The exclusive formation of [4 pi+2 pi] adducts in these reactions ha
s been rationalised by MNDO and AM1 calculations.
