Disclosed herein is an acetylated lactide oligomer-based plasticizer and a method of preparing the same having improved thermal stability, enhanced plasticity and excellent compatibility with a resin, the method, including: (a) synthesizing a lactide oligomer through ring-opening polymerization (ROP) of an initiator and lactide; (b) putting acetic anhydride into the lactide oligomer and performing acetylation; and (c) removing acetic acid generated in step (b) and unreacted acetic anhydride.

A compound having the following formula (I): ##STR00001##
is disclosed. The methods of preparing the compound of formula (I) are also disclosed.

The present invention relates to compounds of formula (I): including any stereochemically isomeric form thereof, or pharmaceutically acceptable salts thereof, for the treatment of, for example, cancer.

A fragrance composition comprising a compound represented by Formula (1) as an active ingredient: ##STR00001## wherein, in Formula (1), R.sup.1 represents a linear, branched, or cyclic alkyl group having 1 to 6 carbon atoms.

The invention relates to ester compounds of the general formula (I) ##STR00001##
to a process for preparation thereof and to the use thereof. These ester compounds may contain a mixture of at least two compounds of the general formula (I).
