dc.description.abstract(+)-펜드러리딘은 식물로부터 유래된 알칼로이드 천연물로서 특징적인 중심구조로 인하여 합성계로부터 많은 주목을 받아왔다. 펜드러리딘과 이의 유도체인 1-아세틸-아스피도알비딘에 대한 여러 합성이 보고 되었지만 이들은 비대칭 전합성과 재현성 있는 N,O-케탈의 형성을 동시에 수행하지는 못했다. 이러한 사실들에 비추어 연쇄적 고리화 촉매 반응을 통해 신뢰성 있는 N,O-케탈의 형성과 5각-6각 접합 이중고리를 만드는 접근을 통해 펜드러리딘의 합성을 시도하고자 한다. 이와 함께 비대칭적 옥신돌의 합성법을 이용, 우리의 합성 전략은 (+)-펜드러리딘에 대한 신뢰성 높은 거울상비대칭적 합성 경로를 제공할 것이다.-
dc.description.abstractThe (+)-fendleridine alkaloid natural product is a botanic natural product and has attracted much attentions from the synthetic community due to its characteristic core structure. Several synthetic efforts have been made toward fendleridine and its congener 1-acetyl-asipdoalbidine. However, these synthesis studies have not established a route either for an enantioselective synthesis or formation of the key N,O-ketal core structure. Taking these facts into account, our synthetic effort focuses on the construction of 5-6 fused bicycle by metal-catalyzed cascade cyclization which offers a reliable route to construct the key N,O-ketal moiety. Combined with an enantioselective oxindole synthesis, the synthetic approach we have developed here have provided a reliable and enantioselective route to (+)-fendleridine.-
