Description

本発明は、スルホニルイミデートの求核剤としての使用を提供するものである。より詳細には、本発明は、一般式(1)で表されるスルホニルイミデートを求核剤として使用し、求核反応生成物を製造する方法に関する。   The present invention provides the use of sulfonyl imidates as nucleophiles. More specifically, the present invention relates to a method for producing a nucleophilic reaction product using the sulfonyl imidate represented by the general formula (1) as a nucleophile.

医薬品産業や農薬産業においては新たな活性化合物の開発のために多数の化合物が製造されてきている。また、近年では有機EL素子などの素子材料として多くの有機化合物が製造されてきている。
このような有機化合物の製造においては、新しい有機化合物の合成手法の開発が望まれてきている。求核反応は有機化合物を製造する際の代表的な化学反応のひとつとして知られており、多くの産業分野で利用されてきている。特に、求核付加反応は、新たなC−C結合やC−N結合を生成させるための化学反応として開発が進められてきている(非特許文献1〜8参照)。しかし、これらの反応にはほぼ等量という多量の塩基が必要とされたり、また求核反応基質化合物の反応性を確保するために反応サイトに隣接する位置に電子吸引基を有していることが必要とされてきた(例えば、非特許文献9〜11参照)。
このために、塩基の使用量が少なく、かつ一般性の高い新しい求核試薬の開発が求められている。
In the pharmaceutical and agrochemical industries, a large number of compounds have been produced for the development of new active compounds. In recent years, many organic compounds have been produced as element materials such as organic EL elements.
In the production of such organic compounds, development of new synthetic methods for organic compounds has been desired. Nucleophilic reaction is known as one of typical chemical reactions in producing organic compounds and has been used in many industrial fields. In particular, the nucleophilic addition reaction has been developed as a chemical reaction for generating a new C—C bond or C—N bond (see Non-Patent Documents 1 to 8). However, these reactions require a large amount of base of approximately the same amount, and have an electron withdrawing group at a position adjacent to the reaction site to ensure the reactivity of the nucleophilic reaction substrate compound. Has been required (see, for example, Non-Patent Documents 9 to 11).
For this reason, development of a new nucleophilic reagent with a small amount of base and high generality is required.
