Aldolisation reactions of silyl keteneacetals with lactone carbonyls can be performed under very mild conditions in good yields in the presence of 5–10 mol-% of TAS-TMSF2.

A general synthetic approach, capable of accessing a diverse range of 3,3-disubstituted quinoline-2,4-diones and 1,8-naphthyridine-2,4-diones via titanium tetrachloride catalyzed C-acylation of silyl ketene acetals is described. The suggested methodological platform is surveyed using different reaction conditions and is applied to the total syntheses of 3,3-diisopentenyl- N-methylquinoline-2,4-dione
