2-Propynyl 2-hydroxybenzoate

Abstract

The title compound, C10H8O3, has been synthesized as part of our investigations into the generation of new antibacterial agents and serves as a building block for the synthesis of compound libraries. The compound crystallizes with two independent molecules in the asymmetric unit. The transoid propynyl ester groups are coplanar with the 2-hydroxybenzoate group with maximum deviations of -0.3507 (3) and 0.1591 (3) Šfor the terminal carbons, with intramolecular O-HO hydrogen bonding providing rigidity to the structure and ensuring that the reactivity of the alkyne is not compromised by steric factors. The propynyl group forms intermolecular C-HO interactions with the phenolic O atom. Supramolecular chains along the b axis are found for both molecules with links by weak O-HO intermolecular interactions in the first independent molecule and C-HO interactions in the second.
