This invention relates to a cyclobutane derivative represented by the following general formula (I):
wherein X represents a group represented by the formula
(wherein R¹ represents an alkyl group having 1 to 5 carbon atoms or an aryl-substituted alkyl group wherein the alkyl group has 1 to 5 carbon atoms;
R² represents a hydrogen atom, an alkyl group having 1 to 5 carbon atoms, a protected hydroxyalkyl group having 1 to 5 carbon atoms or a protected carboxyl group; and
R³ and R⁴ independently represent each a hydrogen atom, an alkyl group having 1 to 5 carbon atoms, a protected hydroxyalkyl group having 1 to 5 carbon atoms, an alkoxy group having 1 to 5 carbon atoms or an aryl-substituted alkoxy group wherein the alkoxy group has 1 to 5 carbon atoms; or
alternately R³ and R⁴ are bound together to thereby form a 3- to 30-membered carbocyclic or heterocyclic ring);
A represents an optionally substituted polymethylene group having 2 to 5 carbon atoms;
Y represents an oxygen or a sulfur atom; and
Z represents an optionally substituted methylene group or an oxygen or a sulfur atom;
which is expected to be useful as reagents, drugs, agricultural chemicals and perfumes as well as an intermediate for the preparation thereof.
