Sonochemical switching from Ionic to Radical Pathways in the Reactions of Styrene and trans-β-Methylstyrene with Lead Tetraacetate

The reactions of sryrene and trans-β-methylstyrene with lead tetraacetate in acetic acid are greatly influenced by ultrasonic irradiation to give products resulting mostly from radical chain pathways, whereas mechanical agitation gives products only from ionic processes.

Nucleo-Palladation-Triggering Alkene Functionalization: A Route to γ-Lactones

An unprecedented strategy for the highly effective synthesis of γ-lactones from homoallylic alcohols was achieved by palladium catalysis in one step. The protocol affords aryl, alkyl, and spiro γ-lactones directly from readily available homoallylic alcohols in good yields with excellent functional group tolerance and high chemoselectivity under mild conditions.

Preparation of titanated alkoxyallenes from 3-alkoxy-2-propyn-1-yl carbonates and (η2-propene)Ti(O-i-Pr)2 as an efficient ester homoaldol equivalent

(equation presented) 3-Alkoxy-2-propyn-1-yl carbonates (2) react with a divalent titanium reagent (η2-propene)Ti(O-i-Pr)2 to afford titanated alkoxyallenes 1 which, in turn, react with aldehydes regiospecifically to provide the corresponding γ-addition products in good to excellent yields, thus affording a convenient method for synthesizing γ-hydroxy esters 3 and/or γ-butyrolactones 4.
