Ethyl 5-oxo-2,3-diphenyl­cyclo­pentane-1-carboxyl­ate

The title compound, C(20)H(20)O(3), was prepared by an acyl­oin-type condensation reaction in the presence of sodium sand and dry ether using ethyl cinnamate as the starting material. The C—O bond lengths for the carbonyl groups are 1.191 (2) and 1.198 (2) Å, while the C—O bond in the ester group is...

description The title compound, C(20)H(20)O(3), was prepared by an acyl­oin-type condensation reaction in the presence of sodium sand and dry ether using ethyl cinnamate as the starting material. The C—O bond lengths for the carbonyl groups are 1.191 (2) and 1.198 (2) Å, while the C—O bond in the ester group is 1.335 (2) Å. The C—C bond lengths in the phenyl groups average 1.375 Å, while the C—C bonds in the cyclo­penta­none ring average 1.525 Å, indicating single C—C bonds in the latter.
