Formal Aza-Wacker Cyclization by Tandem Electrochemical Oxidation and Copper Catalysis

In oxidative electrochemical organic synthesis, radical intermediates are often oxidized to cations on the way to final product formation. Herein, we describe an approach to transform electrochemically generated organic radical intermediates into neutral

Stereocontrolled Oxazolidinone Formation by the Addition of 4,5-Disubstituted Iminodioxolane to Oxirane via a Spiro Compound

4,5-Disubstituted 2-imino-1,3-dioxolanes readily add to oxiranes in the presence of AlCl3, furnishing 1,3-oxazolidin-2-ones in a stereospecific manner, where the configurations of oxiranes and iminodioxolanes are responsible for the configuration of products and the feasibility of the addition, respectively.A preliminary adduct, a spiro compound intermediate, is isolated, and its decomposition to oxazolidinone is demonstrated.

PALLADIUM(O)-CATALYZED CYCLIZATION OF 2-BUTENYLENE DICARBAMATES FORMING 4-VINYL-2-OXAZOLIDONES

2-Butenylene dicarbamates prepared from but-2-en-1,4-diol and isocyanates readily undergo the cyclization in the presence of a phosphine-palladium(O) catalyst to produce 4-vinyl-2-oxazolidones in high yields.
