|Title:||A cyclopropenone route to new pyrrolizidine derivatives|
|Abstract:||New pyrrolizidine derivatives 6 and 7 were prepared from the 1,5-dihydro-2H-pyrrol-2-one 3a via an acidic intramolecular aldol condensation in 16% and 42% yields, respectively. Compound 6 was obtained by dehydration of 7 with p-toluenessulfonic acid in 67% yield.|
