Claim 1

A compound of the formula (I) ##STR14## wherein R represents C 3 -C 6 alkenyloxy, C 3 -C 6 alkenylamino, or di(C 3 -C 6 alkenyl)amino; R 1 represents C 1 -C 8 alkyl, C 1 -C 8 alkoxy, halo, C 1 -C 8 alkylthio, C 3 -C 6 alkenyloxy, amino, C 3 -C 6 alkenylamino, di(C 3 -C 6 alkenyl)amino, ##STR15## wherein R 2 , R 3 , R 4 , R 5 , and R 6 are as defined below, C 1 -C 18 alkylamino, C 1 -C 18 dialkylamino, morpholino, piperidino, pyrrolidyl, a substituted C 1 -C 18 alkylamino, or a substituted C 1 -C 18 dialkylamino, wherein the substituents are selected from amino, cyano, carboxy, alkoxycarbonyl wherein the alkoxy moiety has 1 to 8 carbon atoms, and the groups ##STR16## wherein R 2 represents hydrogen, C 1 -C 8 alkyl, or benzyl; R 3 and R 4 independently represent C 1 -C 8 alkyl, benzyl, or phenethyl, or together with the carbon to which they are attached from a C 5 -C 10 cycloalkyl; and R 5 represents hydrogen, C 2 -C 3 hydroxyalkyl, C 1 -C 8 alkyl, hydroxyl, or oxyl; R 6 represents hydrogen, C 1 -C 8 alkyl, or ##STR17## wherein R 2 , R 3 , R 4 , and R 5 are as previously defined; Y and Y 1 , which may be the same, or different, represent oxy, or ##STR18## wherein R 6 is as previously defined; X represents C 2 -C 12 alkylene, wherein the alkylene chain may be interrupted by an oxy, thio, or ##STR19## radical, C 5 -C 10 cycloalkylene, ##STR20## C 6 -C 12 arylene, or C 8 -C 14 aralkylene; with the proviso that when Y and Y' are oxy, or R 6 is hydrogen, or C 1 -C 8 alkyl, at least one R 1 is, or contains ##STR21## and with the further proviso that R and R 1 are not allyloxy at the same time.
