A relaycatalytic protocol using pyrrolidine and palladium catalysis has been developed for asymmetric synthesis of 1,3-diamine derivatives from 3-substituted 1,3-dienes, sulfuric diamide, and aldehydes. This one-pot, three-component reaction features the advantages of a high atom step economy and operational simplicity, providing an efficient and straightforward access to valuable 1,3-diamines incorporating

본 발명은 ANO1 (Anoctamin 1) 저해 활성을 갖는 신규한 벤조피란 유도체 및 이의 용도에 관한 것이다. 본 발명에 따른 신규 벤조벤조피란 유도체 또는 이의 약학적으로 허용가능한 염은 ANO1에 대한 우수한 저해 활성을 나타내는 바, ANO1이 과발현된 암인 전립선암, 대장암, 식도편평상피세포암, 췌장암, 두경부암 및 유방암의 예방 또는 치료에 있어서, 보다 근본적으로 접근하여 타겟 치료할 수 있을 것으로 기대된다.
Presented herein is a palladium-catalyzed asymmetric (3 + 2) annulation reaction between 1,3-dienes and 2-formylarylboronic acids, proceeding in a cascade vinylogous addition and Suzuki coupling process. Both electron-neutral and electron-deficient 1,3-dienes are compatible under similar catalytic conditions, and distinct regioselectivity is observed via functional-group control of 1,3-diene substrates
