Abstract
The present invention relates to a novel arylisocyanide derivative of the general formula (I) having a tyrosinase activity inhibiting activity and a process for producing the same.
Wherein R, R 1 and R 2 represent each independently a hydrogen, methyl or methoxy, R 3 and R 4 are the case where R 3 is hydrogen R 4 is C 1 -C 4 alkoxycarbonyl C 1 -C 4 alkyl , C 1 -C 4 alkoxycarbonyl C 3 -C 4 alkenyl, C 3 -C 5 alkoxy unsubstituted or substituted by hydroxy or t-butyldimethylsilyloxy, hydroxy C 3 -C 5 alkyl Or when R 4 is hydrogen, R 3 is substituted by C 1 -C 4 alkoxycarbonyl C 1 -C 4 alkoxycarbonyl C 3 -C 4 alkenyl, hydroxy or t-butyldimethylsilyloxy, C 3 -C 5 alkoxy, hydroxyC 3 -C 5 alkyl.
