    摘要: An asymmetric process for the preparation of enantiomerically pure .beta.-D-(-)-dioxolane-nucleosides. The enantiomerically pure dioxolane nucleosides are active HIV agents, that are significantly more effective than the prior prepared racemic mixtures of the nucleosides. The anti-viral activity of the compounds is surprising in light of the generally accepted theory that moieties in the endo conformation, including these dioxolanes, are not effective antiviral agents. The toxicity of the enantiomerically pure dioxolane nucleosides is lower that that of the racemic mixture of the nucleosides, because the nonnaturally occurring .alpha.-isomer is not included.The product can be used as a research tool to study the inhibition of HIV in vitro or can be administered in a pharmaceutical composition to inhibit the growth of HIV in vivo.

    摘要: An acrylate derivative represented by the following general formula (1): (in the formula, R1 represents a hydrogen atom, a methyl group or a trifluoromethyl group; each of R2, R3, R5, R7, R8, R9 and R10 independently represents a hydrogen atom, an alkyl group, a cycloalkyl group or an alkoxy group; each of R4 and R6 independently represents a hydrogen atom, an alkyl group, a cycloalkyl group or an alkoxy group, or R4 and R6 are bonded to each other to represent an alkylene group, —O— or —S—; n represents 0, 1 or 2; and W represents an alkylene group or a cycloalkylene group); an intermediate thereof; a method for producing the same; a polymer compound which is obtainable from polymerization of a raw material containing the foregoing acrylate derivative and which is excellent in solubility in an organic solvent used for the preparation of a photoresist composition; and a photoresist composition containing the polymer compound, an organic solvent and a photo acid generator and having excellent adhesion to substrate and less pattern collapse, are provided.
