This invention provides a novel alkanoyl ester compound represented by general formula (I): STR1 (wherein A is of --, --O--, STR2 B is STR3 l and m are 1 or 2 provided that both are not simultaneously 2, k and n are an integer of 1 or more, respectively, provided that k>n, and R is an alkyl group), a liquid crystal composition containing this compound, a novel alkanoylphenyl compound or a novel alkanoylbiphenyl compound as an intermediate for the production of the above compound, and a method of producing the same. These novel alkanoyl ester compounds are excellent in the stability against light and the like and can take a liquid crystal state at a wide temperature range. Particularly, these compounds form liquid crystals of ferroelectricity having a large spontaneous polarization and a fast response rate by introducing an optically active group into the compound, so that they develop a very excellent effect as a starting material for optoelectronics and its related elements.
