Ionic Liquids as a Convenient Recyclable Medium for the Generation of Transient
Ylides: Syntheses of Oxa and Dioxa-Bridged Polycyclic Systems. —
23- 041 Carbonyl
Under optimized conditions concerning the ionic liquid and the rhodium catalyst, various α-diazo diketones undergo tandem cyclization—cycloaddition reactions with olefins or aldehydes to give polycyclic systems. Significant advantages of the present
method are recovery of rhodium catalyst, reuse of the ionic liquid, replacement of hazardous organic solvents and the resulting high stereoselectivity. — (MUTHUSAMY*,
