ISOSAMIDIN ANALOG AND SAMIDIN ANALOG PRODUCTION METHOD

PROBLEM TO BE SOLVED: To provide a simple method of industrial-scale production of an isosamidin analog or samidin analog. SOLUTION: In the production method, a compound represented by the formula (1) in the figure is 1) senecioylated and 2) acetylated. [X is O or the like; R1 are each independently a C1-3 alkyl group or the like; R2 is H or the like; R3 are each a C1-3 alkyl group; m is an integer from 0 to 2; n is 1 or 2; and the symbol * represents an asymmetric center.] SELECTED DRAWING: None COPYRIGHT: (C)2018,JPOandINPIT

A concise route for the synthesis of biologically interesting pyranocoumarins - Seselin, (±)-cis-khellactone, (±)- quianhucoumarin D, and the (±)-5-deoxyprotobruceol-I regioisomer

An efficient synthesis of pyranocoumarins is achieved starting from 2H-pyrans. This process provides naturally occurring seselin, cis-khellactone, quianhucoumarin D, and the 5-deoxyprotobruceol-I regioisomer. Georg Thieme Verlag Stuttgart.
