DIELS-ALDER REACTIONS OF PYRANOINDOL-3-ONES WITH OLEFINIC COMPOUNDS : SYNTHESIS OF (1,2-DIHYDRO)CARBAZOLES
The Diels-Alder reaction of substituted pyrano indol-3-ones 1 with olefinic dienophiles is described.The role of the substitution pattern on the stability of the obtained 1,2-dihydrocarbazoles is interpreted in terms of electronic and steric effect
