Abstract:
William Pitt and co-workers have created a virtual exploratory heterocyclic library ‘VEHICLe’ containing over 200 unconquered bicyclic heteroaromatic rings, synthetically feasible with potential medicinal interest. Since the publication of the 22 ‘heteroaromatic rings of the future’ by Pitt in 2009, 15 of them have been successfully synthesized as bicyclic or polycyclic forms and evaluated for applications in both biology and material science. This short review presents the critical synthesis associated with innovative synthetic methodologies of the synthetically conquered ring scaffolds from

Abstract:
In the racemic title compound, C19H14N2OS, the two phenyl substituents on the 1,3-thiazine ring are almost perpendicular to the pyridine ring which is fused to the thiazine ring [inter-ring dihedral angles = 87.90 (8) and 85.54 (7)°]. The dihedral angle between the two phenyl rings is 75.11 (7)°. The six-membered thiazine ring has an envelope conformation with theortho-related C atom forming the flap. The crystals exhibit face-to-edge aromatic-ring interactions with the nearest C—H...C distance equal to 3.676 (3) Å.

Ce manuscrit porte sur la synthèse et les applications d'une nouvelle série de composés hétéroaromatiques : les 4H-pyrido[e][1,3]oxazin-4-ones. La première partie de ce manuscrit présente la préparation de ces squelettes via une réaction d'O-arylation intramoléculaire. La seconde partie du manuscrit repose sur la réactivité de ces entités chimiques et de leur utilisation en tant qu'intermédiaires de synthèse. La fonctionnalisation des 4H-pyrido[e][1,3]oxazin-4-ones, via des réactions de couplage pallado-catalysées, a permis d'obtenir des systèmes polyfonctionnalisés plus complexes. Les pyrido-
