Description

本発明は、各種の医薬、農薬、香料、染料、合成樹脂、電子材料などの合成中間体等として有用なN’−ホモアリルアシルヒドラジド類の製造方法に関するものである。   The present invention relates to a method for producing N′-homoallylacyl hydrazides useful as synthetic intermediates for various pharmaceuticals, agricultural chemicals, fragrances, dyes, synthetic resins, electronic materials and the like.

N’−ホモアリルヒドラジド類は、反応性の高いアリル基を含む複数の官能基を有し、化学変換によって様々な合成中間体に変換可能な化合物である。更に、窒素−窒素結合を接触還元やヨウ化サマリウムなどによって切断することで広範な用途を持つホモアリルアミンにも容易に変換可能な有用な化学品である。N’−ホモアリルヒドラジド類の合成法としては、アシルヒドラゾン類とテトラアリルスズなどのアリル化剤とをルイス酸触媒下にて反応させる方法(非特許文献1)がしばしば用いられてきたが、これらの方法は、アリル化剤が水分に対して不安定である、副生する金属化合物が人体や環境に悪影響を与える、などの問題があった。   N'-homoallyl hydrazides are compounds that have a plurality of functional groups including highly reactive allyl groups and can be converted into various synthetic intermediates by chemical conversion. Furthermore, it is a useful chemical that can be easily converted to homoallylamine having a wide range of uses by cleaving the nitrogen-nitrogen bond by catalytic reduction or samarium iodide. As a method for synthesizing N′-homoallyl hydrazides, a method of reacting acylhydrazones with an allylic agent such as tetraallyltin in the presence of a Lewis acid catalyst (Non-patent Document 1) has been often used. These methods have problems that the allylic agent is unstable with respect to moisture, and that the by-product metal compound adversely affects the human body and the environment.

近年、アルデヒド類と穏和なアリル化剤であるアリルトリクロロシランとを、金属元素を含まずに配位能を有する、尿素、ジメチルホルムアミド(DMF)、ピリジン−N−オキシド、ホスホロアミド類、ホスフィンオキシド類などのルイス塩基触媒により活性化する方法(非特許文献2〜8)が報告されているが、その活性化能はアシルヒドラゾン類のアリル化反応に用いるには不十分である。更に、ジメチルスルホキシド(DMSO)が、アリルトリクロロシランによるアシルヒドラゾン類のアリル化反応に有効であることも報告されている(非特許文献9〜11)が、DMSOは酸性条件下や酸化的条件下で安定性に欠けるという欠点を有している。
そこで、人体や環境に悪影響を与えるような金属試薬を用いることなく、温和な条件下で、安価で且つ安定性の高い試薬を用いてアシルヒドラゾン類のアリル化反応を達成する方法が求められていた。
In recent years, urea, dimethylformamide (DMF), pyridine-N-oxide, phosphoramides, phosphine oxides, which have a coordination ability without containing metal elements, with aldehydes and mild allylating agent, allyltrichlorosilane Although a method of activation with a Lewis base catalyst such as Non-patent Documents 2 to 8 has been reported, its activation ability is insufficient for use in the allylation reaction of acylhydrazones. Furthermore, it has also been reported that dimethyl sulfoxide (DMSO) is effective for allylation of acylhydrazones with allyltrichlorosilane (Non-Patent Documents 9 to 11), but DMSO can be used under acidic conditions or oxidative conditions. And lacks stability.
Therefore, there is a need for a method for achieving an acylation reaction of acylhydrazones using an inexpensive and highly stable reagent under mild conditions without using a metal reagent that adversely affects the human body and the environment. It was.

Further, when immobilized phosphine oxide is used as the phosphine oxide, after the reaction, it is removed from the reaction system by filtration, and then a normal post-treatment operation may be performed. The recovered immobilized phosphine oxides can be reused repeatedly only by a simple washing operation.

Is usually 0.1 to 5 equivalents, preferably 1 to 3 equivalents. The reaction solvent may be any solvent that dissolves the reaction substrate and does not interfere with the allylation reaction. For example, halogenated hydrocarbons such as dichloromethane and chloroform, diethyl ether, tetrahydrofuran And ether solvents such as are preferable. The reaction temperature can be arbitrarily selected between minus 78 ° C. and room temperature, but is usually carried out at a low temperature of 0 ° C. or less. The reaction time naturally varies depending on the reaction temperature, the type and amount of phosphine oxides, the type and amount of substrate and allylating agent, and other reaction conditions, but is usually from several tens of minutes to several tens of hours.

斯くして、人体や環境に有害な金属試薬を使うことなく、穏和な反応条件下、取り扱いの容易な試薬を用いて、様々な用途があり有用な化合物であるN’−ホモアリルアシルヒドラジド類を高収率で得ることが可能となった。
