Lactones, XI: Syntheses of 4,9-Dihydropyrano-indol-1(3H)-ones from &α-Ethoxalyl-&γ-lactones

Lehmann, Jochen,Ghoneim, Khadiga M.,El-Fattah, Bothaina Abd,El-Gendy, Adel A.

, p. 22 - 29 (1987)

Cleavage and decarboxylation of the α-ethoxalyl-γ-lactones 1a-d followed by treatment with phenylhydrazines yield the hydrazones 4a-l, which can be rearranged to the indololactones 5a-m.Starting from the δ-lactones 6 and 10, the same reactions lead to indoles without lactone ring closure.
