Synthesis of N-heterocyclic compounds via ene-yne metathesis reactions
Propargylamino and allylamino derivatives of cyclohexene and norbornene were subjected to tandem metathesis reactions with first and second generation Grubbs' catalysts 1 and 2. Results show that the method is compatible with suitably protected nitrogen-containing compounds. Cyclohexenes gave intriguing results in terms of the possibility to perform ring rearrangement metathesis (RRM) reactions, showing a difference with the analogous allyl and propargyl ether substrates.
Alkene and enyne metathesis reactions on allylic and propargylic amines
Treatment of cis-4,5-diaminocyclohexene derivatives bearing allyl or propargyl groups on the nitrogen atoms, with first or second generation Grubbs metathesis catalysts, results in initiation of metathesis cascades which include ring-opening of the unstra
