Description

크로마놀 유도체의 신규한 제조방법Novel Method for Preparing Chromanol Derivatives
본 명세서는 2015년 8월 4일에 한국특허청에 제출된 한국 특허 출원 제 10-2015-0110248호의 출원일의 이익을 주장하며, 그 내용 전부는 본 명세서에 포함된다. This specification claims the benefit of the application date of Korean Patent Application No. 10-2015-0110248 filed with the Korea Intellectual Property Office on August 4, 2015, the entire contents of which are incorporated herein.
본 발명은 광학 활성을 가지는 크로마놀 유도체의 신규한 제조방법에 관한 것이다.The present invention relates to a novel process for preparing chromamanol derivatives having optical activity.
키랄 크로마놀(chromanol) 유도체 화합물은 의약 및 화학 분야에서 다양한 활성을 가지는 물질로써, 현재 개발 중인 의약품 등에서도 키랄 크로마놀 구조 화합물이 많이 존재한다. 그런데, 동일한 분자식을 가진 크로마놀 유도체 화합물이라도 3차원 입체구조에 따라 약효가 매우 다르게 나타나는 경우가 많다. 그러므로 키랄 크로마놀 유도체 화합물을 입체선택적으로 합성하는 것은 의약합성 및 유기합성에서 대단히 중요하다. 그러나, 키랄 크로마놀 유도체 화합물의 중요성에도 불구하고, 키랄 크로마놀 유도체 화합물을 손쉽게 합성하는 방법은 많이 보고되고 있지 않다. Chiral chromanol (chromanol) derivative compound is a substance having a variety of activities in medicine and chemistry, and there are many chiral chromanol structural compounds in the currently developed medicines. However, even in the case of a chromamanol derivative compound having the same molecular formula, the drug efficacy is often very different depending on the three-dimensional conformation. Therefore, stereoselective synthesis of chiral chromanol derivative compounds is of great importance in medicinal and organic synthesis. However, despite the importance of chiral chromanol derivative compounds, many methods for easily synthesizing chiral chromanol derivative compounds have not been reported.
국제공보 WO 2007/072146에는 5,7-디플루오로크로만-4-온을 출발물질로 사용하여 5,7-디플루오로크로만-4-올을 제조하는 방법이 기재되어 있다. 그러나 상기 특허에 기재된 제조방법은 1차 결정화 공정에서 86 %ee 값의 낮은 광학 입체 선택성을 가지며 광학 입체 선택성을 증가 시키기 위해 정제공정이 반드시 필요하다고 명기되어 있다. 이러한 이유로 상기 특허에 기재되어 있는 방법은 제조 단가가 높으며 추가된 정제 공정에도 불구하고 58%의 매우 낮은 수득률을 가진다. 또한 1차 고체화 분리에 실리카겔 상에서의 컬럼 크로마토그래피를 사용함으로 인하여 대량생산의 공정에는 적합하지 않은 문제점이 있다.International publication WO 2007/072146 describes a process for preparing 5,7-difluorochroman-4-ol using 5,7-difluorochroman-4-one as starting material. However, the manufacturing method described in the patent has a low optical stereoselectivity of 86% ee value in the primary crystallization process, it is specified that the purification process is necessary to increase the optical stereoselectivity. For this reason the process described in this patent is expensive to manufacture and has a very low yield of 58% despite the added purification process. In addition, due to the use of column chromatography on silica gel for primary solidification separation, there is a problem that is not suitable for mass production processes.
이에 따라, 의약 및 화학분야에서 매우 중요한 약물 특이 분자단으로 알려진 광학활성을 갖는 크로마놀 유도체를 고순도의 광학품질 및 고수율로 산업적으로 대량생산할 수 있는 신규한 제조방법이 필요한 실정이다.Accordingly, there is a need for a novel manufacturing method capable of industrially mass-producing chromamanol derivatives having optical activity, which are known as drug specific molecular groups, which are very important in medicine and chemical fields, with high optical quality and high yield.
