A versatile synthesis of azidolactones through azidation and cyclization of carboxylic acids onto alkenes has been developed. Based on either photoredox or palladium catalysis, (1,1) and (1,2) azido lactones can be selectively synthesized. The choice of catalyst and benziodoxol(on)e reagent serving as azide source was essential to initiate either a radical or Lewis acid mediated process with divergent outcome. These transformations were carried out under mild conditions using a low catalyst loading and gave access to a large scope of azido lactones.

A catalytic three-way rendezvous: Terminal alkynes undergo metal vinylidene formation, anti-Markovnikov hydration to give a metal acyl complex, and conjugate addition to produce synthetically useful 1,4-dicarbonyl compounds under ruthenium catalysis. This one-pot three-component coupling reaction is a useful platform for further exploration in alkyne functionalization.

Tetramethylammonium pentacarbonyl(1-oxidoalkylidene)chromium(0) complexes are oxidized with bis(2,2,6,6-tetramethyl-3,5-heptanedionato)copper(II) to generate acyl radicals which react electron-deficient olefins, giving intermolecular addition products.
A Novel, Two-step, Mild and Simple Synthesis of β-, γ-, and δ-Oxo Esters from ω-Nitro Esters.
Ballini, Roberto,Bosica, Giovanna
, p. 2901 - 2912 (2007/10/02)
A convenient, mild, and simple synthesis of β-, γ-, and δ-oxo esters was achieved from ω-nitro esters.A solvent-free nitroaldol reaction of the ω-nitro esters 2 with the aldehydes 1 on alumina, followed by in situ dehydration, with addition of dichloromethane and warming gave the conjugated nitroalkenes 3, which can be converted into the carbonyl derivatives 4 by sodium hypophosphite.
