Alkyl phenyl 2,3-epoxycarboxylates from the well-known Darzens glycidic esters synthesis react under very mild conditions with pyridinium-poly-hydrogen fluoride to give corresponding 3-fluoro 3-phenyllactates in almost quantitative yields with a high regio and stereoselectivity.

A convenient synthetic method to indoles from anilines and cyanoepoxides was developed under the catalysis of BF3·OEt2 or AlCl3 in alcohols. The reaction involves a tandem reaction of the regiospecific ring-opening of cyanoepoxides with anilines, elimination of cyanide, intramolecular aromatic electrophilic substitution, and water elimination. The Lewis acid generated protic acid is an efficient catalyst

The indirect electrolytic oxidation of ketones (1) in methanolic sodium cyanide was studied using iodide ion as a mediator. The product and the reactivity of ketone were dependent on the nature of the alkyl groups attached to the carbonyl group. Thus, 2-alkyl and 2,2-dialkyl ketones afforded the corresponding oxiranecarbonitriles 2 along with small amounts of methyl oxiranecarboximidate 3, whereas acetophenones exclusively yielded benzoylpropanedinitriles 4.
