- Tandem Chloropalladation/Cyclization and Dearomative Cyclization toward Functionalized Tricyclic Bridged [3.2.1] Skeleton Compounds
-
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, i.e., protonolysis, β-hydride elimination, and chlorination of the C-Pd bond, were suppressed to the lowest level under mild reaction conditions.

- Syntheses of 3,7-Dimethyl-8-hydroxy-6-methoxyisochroman, the 3,7-Dimethyl-6-hydroxy-8-methoxy Isomer, and Their Ester and Ether Derivatives: Plant Growth Regulatory Activity
-
A systematic invesitgation of ester and ether derivatives of 3,7-dimethyl-8-hydroxy-6-methoxyisochroman and 3,7-dimethyl-6-hydroxy-8-methoxyisochroman has established that all of the derivatives synthesized exhibited activity in the wheat coleoptile assay, with several of the compounds being more active than the parent systems.
