摘要

The first successful inverse electron-demand Diels–Alder has been demonstrated with the 2- pyrone methyl coumalate in conjunction with substituted indoles. Utilizing 1-alkyl-3- chloroindoles as the electron-rich dienophile efficiently generates carbazoles without the need for additional metal catalysts. Through a thermal, one-pot Diels–Alder/decarboxylation/ elimination domino sequence, access to a class of 3-methylcarbazoles is rapidly ...
