ETUDE DE L'ACTION DES ALKYLMAGNESIENS PRIMAIRES ET ARYLMAGNESIENS SUR LES ANHYDRIDES TRICYCLIQUES PONTES

The reaction of primary alkyl and aromatic Grignard reagents with bridged tricyclic dicarboxylic anhydrides gives the corresponding dialkylated tricyclic lactones via di-addition process.The lactones were transformed by retro-Diels-Alder reaction into 4,4-dialkylated butenolides.

ALKYLATION DES LACTONES TRICYCLIQUES PONTEES. APPLICATION A LA SYNTHESE DES BUTENOLIDES TRISUBSTITUES EN 2 ET 4.

Disubstituted endo tricyclic lactones have been prepared by the reaction of primary alkylmagnesium compounds with the endo bicyclohept-5-ene-2,3 dicarboxylic anhydride.These lactones were alkylated and transformed into corresponding 3,5,5-trialkyl-2(5H)-furanones.
