Tandem Chloropalladation/Cyclization and Dearomative Cyclization toward Functionalized Tricyclic Bridged [3.2.1] Skeleton Compounds
摘要:
A palladium-catalyzed tandem reaction is reported that involves chloropalladation/cyclization and dearomative cyclization to construct a tricyclic bridged [3.2.1] carbocyclic-skeleton and oxa- and aza-skeletons. In this domino process, a level of ring strain and other competitive reactions, Le, protonolysis, beta-hydride elimination, and chlorination of the C-Pd bond, were suppressed to the lowest level under mild reaction conditions.

Provided is a 2H-chromene compound or a derivative thereof which has an excellent S1P1 agonist action. The 2H-chromene compound or derivative is particularly useful for preventing and/or treating a disease induced by undesirable lymphocyte infiltration or a disease induced by abnormal proliferation or accumulation of cells.
