Abstract:
The reaction of ethyl 3-bromo-3-phenyl-propano-ate with pentane-2,4-dione, in the presence of palladium(II) acetate and triphenyl-phosphine, in dimethyl-formamide, unexpectedly gave the title product, C(16)H(20)O(4). The mol-ecule contains one chiral C atom but the crystal is racemic. In the crystal, neighboring mol-ecules form a chain along [100] through three weak C-H⋯O inter-actions. Furthermore, a double-stranded structure is formed through weak C-H⋯O inter-actions between two parallel chains.

Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.
