A compound represented by the formula (I), an optically active isomer thereof, or a pharmaceutical acceptable salt thereof: wherein X represents CH or N; 1 represents a C1-C12 alkyl; R2 represents a hydrogen atom, or the like; R' represents a C1-C6 alkyl or the like; q represents 0 or an integer of 1 to 7; Y represents a C1-C6 alkyl or the like; p represents 0 or an integer of 1 to 5; R represents a 2,3-dihydroindolyl or the like, which is used for preventive and/or therapeutic treatment of a disease caused by tau protein kinase 1 hyperactivity such as a neurodegenerative diseases (e.g. Alzheimer disease).
with vinylene carbonate for the synthesis of isoquinolinones and pyridinones has been developed. This protocol employing inexpensive Co(III) as the catalyst tolerated diverse functional groups and substitution patterns, affording the target products with good to excellent yields. The synthetic utility of this transformation was demonstrated by a three-step synthesis of gusanlung D, 8-oxopseudopalmatine
