  • Patent number: 8903907
    Abstract: Provided is a relationship support apparatus capable of preventing a user from inconsistently applying for relationships. An receiving section (32) receives an input of identification information of a desired relationship partner user, and further receives an input of identification information of the relationship-seeking user. A determination section (38) determines, based on the identification information of the relationship-seeking user and the identification information of the desired relationship partner user, whether or not an agreement has been reached on the relationship between the relationship-seeking user and the desired relationship partner user. A suspension section (40) suspends, based on a result of the determining performed by the determination section (38), the relationship-seeking user and the desired relationship partner user from carrying out a relationship-seeking activity with respect to another user.
    Type: Grant

  • Patent number: 7041820
    Abstract: There is provided a method by which various compounds (1) having a carboxyl group in the molecule have the carboxyl group converted to a (dioxolenon-4-yl)methyl ester at low cost, in a simple way and at high yield. The process for producing compounds of formula (3) according to the reaction scheme shown below comprises reacting carboxylic acids of formula (1) with 4-chloromethyldioxolenone compounds of formula (2) in a solvent in the presence of both a phase transfer catalyst and a metal iodide: [where Q represents an organic group, M represents a hydrogen atom, an alkali metal, an alkaline earth metal or a transition metal, R1 and R2 represent a hydrogen atom, an optionally substituted (C1-6 alkyl group or phenyl group)].

  • Publication number: 20040152894
    Abstract: 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).
