Triflic acid mediated dealkylative lactonisation via NMR-observable alkyloxonium intermediates
Munoz, M. Paz,Lloyd-Jones, Guy C.
experimental part, p. 516 - 524 (2009/07/19)
Trifluoromethanesulfonic acid (TfOH) efficiently induces the dealkylative cyclisation of pent-4-enoates to generate γ-lac-tones with high selectivity. For primary alkyl esters bearing an additional alkene, only monolactonisation occurs, even in the presen

, p. 277 - 281 (2007/10/02)
A new approach to the synthesis of Δα,β-butenolides from γ-butanolides by means of the electrolytic oxidation of α-carboxy-α,γ-dimethyl-γ-butyrolactone (3b) and its α-carboxy-α-methyl analog (3d) resulted in predominant formation of the endocyc
