一般的な説明

Ethyl 2,4-dihydroxy-6-methylbenzoate is also referred as ethyl orsellinate. It was isolated from chloroform extract of Peltigera aphthosa. It is one of the product formed during alcoholyses of lecanoric acid.

Structure and conformation

The mol-ecular structure of Ethyl 2,4-dihydroxy-6-methylbenzoate contains a methyl group, two hydroxyl groups, and a carboeth-oxy group, which are attached to C2, C4, C6 and C7 of the central benzene ring, respectively. An intra-molecular O3—H3···O1 hydrogen bond stabilizes the mol-ecular conformation. In the crystal, O4—H4···O3ⁱ and C3—H3A···O4ⁱⁱ hydrogen bonds link the mol-ecules into double strands parallel to the direction. In the solid state, the compound also forms offset slanted stacks of alternating inversion-related mol-ecules along the a-axis direction[1].
