摘要
The present invention relates to novel aryl isocyanide derivatives of the following general formula (I) having a tyrosinase activity inhibiting ability and a method 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 3 -C 5 alkoxy, hydroxy C 3 -C 5 alkyl substituted or unsubstituted by C 1 -C 4 alkoxycarbonyl C 3 -C 4 alkenyl, hydroxy or t-butyldimethylsilyloxy Or when R 4 is hydrogen, R 3 is C 1 -C 4 alkoxycarbonyl C 1 -C 4 alkyl, C 1 -C 4 alkoxycarbonyl C 3 -C 4 alkenyl, hydroxy or t-butyldimethylsilyl C 3 -C 5 alkoxy, hydroxy C 3 -C 5 alkyl unsubstituted or substituted by oxy.
