Claim:
A 1-heterodiene derivative represented by formula (1) or salt thereof: wherein Q 1 represents an optionally substituted C2-6 alkenyl group, an optionally substituted C2-6 alkynyl group, an optionally substituted C3-6 cycloalkyl group, an optionally substituted C4-8 cycloalkenyl group, an optionally substituted C6-10 aryl group, an optionally substituted benzyl group or an optionally substituted heterocyclic group, W represents hydrogen atom or an optionally substituted C1-6 alkyl group, X represents oxygen atom, sulfur atom or N-Q 2 (Q 2 represents an optionally substituted C2-6 alkenyl group, an optionally substituted C2-6 alkynyl group, an optionally substituted C3-6 cycloalkyl group, an optionally substituted C4-8 cycloalkenyl group, an optionally substituted C6-10 aryl group, an optionally substituted benzyl group, an optionally substituted C6-10 aryloxy group, an optionally substituted C6-10 arylamino group or an optionally substituted heterocyclic group), Y represents oxygen atom, sulfur atom or N-Q 3 (Q 3 represents an optionally substituted C2-6 alkenyl group, an optionally substituted C2-6 alkynyl group, an optionally substituted C3-6 cycloalkyl group, an optionally substituted C4-8 cycloalkenyl group, an optionally substituted C6-10 aryl group, an optionally substituted benzyl group, an optionally substituted C6-10 aryloxy group, an optionally substituted C6-10 arylamino group or an optionally substituted heterocyclic group), provided that when X represents oxygen atom or sulfur atom, Y represents N-Q 3 , when X represents N-Q 2 , Y represents oxygen atom or sulfur atom, A represents oxygen atom, sulfur atom, sulfonyl group or sulfinyl group, n represents an integer of 1 to 4, R 1 represents an optionally substituted C1-6 alkyl group, an optionally substituted C2-6 alkenyl group, an optionally substituted C2-6 alkynyl group, an optionally substituted C3-6 cycloalkyl group, an optionally substituted C4-8 cycloalkenyl group, an optionally substituted C6-10 aryl group, an optionally substituted heterocyclic group, an optionally substituted C1-11 acyl group, an optionally substituted (1-imino) C1-6 alkyl group, an optionally substituted hydroxy group, an optionally substituted amino group, an optionally substituted mercapto group, a substituted sulfonyl group, a substituted sulfinyl group, a silyl group, a halogen group, cyano group or nitro group, m represents an integer of 0 to 10, when m is 2 or more, R 1 may be the same or different from each other, more than one R 1 may bond together to form an optionally substituted 3- to 8-membered ring, the 1-heterodiene derivative exists in E-form, Z-form or a mixture thereof according to the carbon-carbon undefined double stereo bond in formula (1).
