Abstract

The chiral title compound, C(7)H(12)O(2), a lactone derivative, features a seven-membered ring that adopts a chair conformation. The crystal structure is stabilized by weak C-H⋯O inter-actions occurring in the (100) plane. The absolute configuration was assigned on the basis of the enantioselective synthesis.

The packing of one layer found in the crystal structure of (I) viewed down the a* direction. Molecules are connected by short C–H···O contacts in the (1 0 0) plane. Only one set of short contacts (dashed lines) is shown for clarity. The symmetry codes are: (i) 2 - x, -1/2 + y, -z; (iii) 2 - x, 1/2 + y, -z; (iv) x, y, z - 1.
