| abstract |
This invention relates to a method of using compounds selected from those of the following formula: <IMAGE> wherein R1 is hydrogen, alkyl or alkenyl; R2 is hydrogen, alkyl, cycloalkyl or mononuclear aryl or R1 and R2, taken together with the carbon atom to which they are attached, form a cycloalkyl or cyloalkoxyalkyl; R3 is hydroxy, alkyl, alkoxycarbonyl, hydroxy lower alkyl or a radical of the formula: -C(=Y)NR4R5 wherein R4 is hydrogen, alkyl, or alkenyl, R5 is alkyl, alkenyl carbalkoxy, or mononuclear aryl, or R4 and R5 may be joined together with the nitrogen atom to which they are attached to form a 5- to 7-membered heterocyclic ring having from 1 to 3 hetero atoms; Y is O or S; X is alkyl, alkoxycarbonylalkyl or cyano; m is an integer of 0 to 2 and n and n' are integers each having a value of 1 to 2 and the dotted line indicates an optional carbon to carbon double bond, compositions containing said compounds as insect repellents and to novel compounds. |
