Abstract
Indole lactones 8 and 14 were synthesized as a means of functionalizin g the 1-isopropyl substituent of the indole nucleus. Lactone 8, upon r eduction with diisobutylaluminum hydride, produces lactol 9 which beha ves like a masked hydroxy aldehyde and undergoes a Horner-Emmons react ion with triethyl phosphonoaceate to give alpha,beta-unsaturated ester 3 which possesses a hydroxyl group on the 1-isopropyl moiety.
