A novel synthesis of GSK1265744, a potent HIVintegraseinhibitor, is described. The synthesis is highlighted by an efficient construction of the densely functionalized pyridinone core as well as a highly diastereoselective formation of the acyl oxazolidine moiety. The latter exploits the target molecule’s ability to chelate to Mg2+, a key feature in the integraseinhibitor’s mechanism of action.

An efficient method for the preparation of β-amino-α,β-unsaturated carbonylcompounds is demonstrated. Bench-stable sodium 3-oxo-enolates were prepared from carbonylcompounds, and reacted with amines in the presence of an acid and a desiccant. DFT studies revealed contrasting mechanisms toward the reactivity of aliphatic amines in protic solvents and aromatic amines in aprotic solvents. While the

NMR of enaminones. Part 8—1H, 13C and 17O NMR spectra of primary and secondary 1,2‐disubstituted enaminones: configuration, conformation and intramolecular hdydrogen bonding
The H-1,C-13 and O-17 NMR spectra for four series of C-2-substituted enaminones are reported: MeCO(Me)C=CHNHR (1), EtCO(Me)=CHNHR (2), PhCO(Me)C=CHNHR (3) and MeCO(Me)C=CHNHR (4). The H-1, C-13 and O-17 NMR data for these enaminones show that 1 and 2 exist as mixtures of E- and Z-forms, 3 exists mainly in the E-form and 4 is in the Z-form. The E- and Z-forms exist in the E-s-E-s-E and Z-s-Z-s-E conformations, respectively. The O-17 shift values of the carbonyl groups in the four series of enaminones show that the influence of N substituents is essentially identical and is additive. The shielding of the carbonyl O atom by intramolecular hydrogen bonding (Delta delta(HB)), ca. - 30 ppm, is dependent on the donor ability of the amino groups and the type of C-l and C-2 substituents. Correlations of the H-1, C-13 and O-17 NMR data between the E- and Z-forms of enaminones are excellent. (C) 1998 John Wiley & Sons, Ltd.
