Silver-catalyzed chemodivergent assembly of aminomethylated isochromenes and naphthols

A silver-catalyzed chemodivergent cyclization of alkyne-tethered aldehydes with aminals to aminomethylated 1H-isochromenes and naphthols is described by tuning the reaction conditions. The reaction exhibits broad substrate generality and functional group compatibility. Mechanistic studies have disclosed that the aminomethylated naphthols are generated from the resulting N,O-aminal containing isochromenes via a silver-catalyzed unusual rearrangement process.

Intramolecular 1,3-dipolar nitrone cycloaddition route to bicyclic fused enediyne

Bicyclic isooxazolidinyl enediynes 1 and 2 have been prepared by intramolecular nitrone cycloaddition between the two arms of an acyclic enediyne precursor 13. The reaction is highly regioselective and the two configurational isomers have similar onset te
