An efficient synthesis of diarylallenylidene pentacarbonyl chromium and tungsten com­plexes is presented. Irradiation of M(CO)6 in THF affords (CO)sM[THF], Substitution of the THF ligand by diarylpropargylalcoholate and subsequent desoxygenation with COCF gives the title compounds in good yield. (The structure of diphenylallenylidene pentacarbonyl chromium has been determined by X-ray structure analysis

In a synthetic approach to (+)-dioncophylline C (1), a coupling between the chiral oxazoline (3) and the Grignard reagent obtained from bromide (4) gave the major biaryl (5) and the minor biaryl (12) in good yield and high diastereoselectivity (yield 70%; ratio 91:9). The stereochemistry of the major biaryl (5) was confirmed by X-ray structure analysis of the derived crystalline iodide salt (13).

An efficient method for the stereoselective synthesis of α-methylene-γ-lactams via quaternary 3-aminooxindoles with very high selectivity (up to 98% ee) is described. The methodology leads to the construction of sterically congested chiral quaternary 3-aminooxindole adducts in good yield and with moderate to excellent diastereoselectivity (dr up to 95:5). The relative stereochemistry of the chiral quaternary 3-aminooxindoles adduct and the spiro-α-methylene-γ-lactam was confirmed to be syn by single-crystal X-ray structure analysis. Furthermore, the α-methylene-γ-lactam was successfully transformed into a range of chiral synthons.
