Abstract
beta-Trifluoracetyl-N-methyl-2-pyrrolidone undergoes once or twice the Robinson annelation with methylvinylketone. The spiro compound 6 can be trifluoroacetylated to the corresponding 1,3-diketone 8 for heterocyclizations with bis-nucleophiles. Furthermore, 6 furnishes spirocyclohexadienone 15 with potential for aromatisation.
