O,ω-Unsaturated N-tosyl alkoxyamines undergo unexpected RhIII-catalyzed intramolecular cyclization by oxyamination to produce oxygen-containing heterocycles. Mechanistic studies show that an aziridine intermediate seems to be responsible for the formation of the heterocycles, possibly via a RhV species.

General and efficient syntheses of 4H-cyclohepta- and 4H-cyclopentafurans (4 and 5) have been accomplished employing the intramolecular dipolar cycloaddition based fused furan construction strategy.Treatment of the oximes (20 and 29), readily pre
Intramolecular Olefinic Aldehyde Prins Reactions for the Construction of Five-Membered Rings
Andersen, Niels H.,Hadley, Stephen W.,Kelly, James D.,Bacon, E. R.
, p. 4144 - 4151 (2007/10/02)
Four catalysts (Me2AlCl SnCl4 > EtAlCl2 > Et2AlCl) for the cyclization of olefinic aldehydes by an internal Prins mechanism have been compared by using systems that afford five-membered rings by type I and type II ene processes.Stannic chloride and Me
