Molecular Recognition of α,β-Unsaturated Carbonyl Compounds Using Aluminum Tris(2,6-diphenylphenoxide) (ATPH): Structural and Conformational Analysis of ATPH Complexes and Application to the Selective Vinylogous Aldol Reaction
Various alpha,beta-unsaturated carbonyl compounds were coordinated with aluminumtris(2,6-diphenylphenoxide) (ATPH) to give the corresponding Lewis acid-base complexes in a distinctive coordination fashion (selective coordination). ATPH recognizes carbonyl substrates and subsequently orients itself as it forms a stable complex through selective coordination with the carbonyl oxygen. Selective coordination
