    摘要: Processes for producing a compound represented by the formula (1), which includes an acrylic acid derivative and is useful as an agricultural chemical or medicine. One of the processes comprises the step of formulating a compound (3) and converting the OH of the resultant compound (2) into OR″. The first step comprises reacting a formic or orthoformic ester in the presence of a Lewis acid and a base. The second step comprises reacting the compound with R″OH or with R″OH and CH(OR″)3 under acidic conditions or using a phase-transfer catalyst in a two-phase system and regulating the base and the concentration thereof to stereoselectively synthesize the target compound. In another, process, the compound is efficiently produced without isolating the compound. The compound can also be produced without the compound (2).

    摘要: The invention provides novel processes for preparing efficiently compounds of general formula (1) (wherein R1 and R2 are each independently hydrogen, optionally substituted C1-C10 alkyl, C3-C14 hydrocarbyl bearing alicyclic skeleton, or the like) and initermediates thereof. Compounds of general formula (I) can be prepared by subjecting compounds of general formula (II) and/or salts thereof to cyclization hydrolysis in an aqueous basic solution. Further, compounds of general formula (II) can be prepared from industrially easily available diaminomaleonitrile in a high yield.

    摘要: A method of detecting deficiency of an aperture used in a charged-particle-beam exposure process employing at least two exposure columns is disclosed, where each of the two exposure columns passes a charged-particle beam through the aperture formed through a mask to shape a cross section of the charged-particle beam before exposing the charged-particle beam onto an object. The method includes the steps of mounting masks having the same aperture to the at least two exposure columns; scanning, in each of the at least two exposure columns, the charged-particle beam over an area containing a mark on a surface substantially at the same height as the object after passing the charged-particle beam through the same aperture; obtaining, in each of the at least two exposure columns, a signal waveform corresponding to the scan by detecting charged particles scattered by the mark; and comparing the signal waveform between the at least two exposure columns.

    摘要: A mask for exposure of an object by an electron beam is formed of a plate of material which blocks the electron beam and which has plural pattern exposure blocks defined therein, each having one or more aperture defining regions therein and, when selected, determining the shaping of the electron beam passing therethrough so as to expose a respective pattern on an object. Each aperture-defining region has one aperture or plural, spaced apertures formed respectively therein, having a total area size, selected to be smaller than the area size of the aperture defining region in accordance with controlling the current level of an electron beam passing therethrough, while reducing Coulomb interaction of the electron beam passing through the aperture or apertures of each aperture defining portion of the pattern exposure block.
