OG Complex Work Unit Drawing
wherein
one of X1, X2 and X3 indicates a single bond and the others independently indicate a single bond or an optionally substituted C1-6 alkylene group, an optionally substituted C2-6 alkenylene group, an optionally substituted C2-6 alkynylene group, —O—, —S—, —CO—, —SO—, —SO2—, —N(R6)—, —N(R7)—CO—, —CO—N(R8)—, —N(R9)—CH2—, —CH2—N(R10)—, —CH2—CO—, —CO—CH2—, —N(R11)—S(O)m—, —S(O)n—N(R12)—, —CH2—S(O)p—, —S(O)q—CH2—, —CH2—O—, —O—CH2—, —N(R13)—CO—N(R14)— or —N(R15)—CS—N(R16)— wherein R6, R7, R8, R9, R10, R11, R12, R13, R14, R15 and R16 independently indicate a hydrogen atom, a C1-6 alkyl group or a C1-6 alkoxy group; and m, n, p and q are independent of each other and each independently indicates an integer of 0, 1 or 2, provided that X1, X2 and X3 do not indicate a single bond at the same time;
A1, A2 and A3 are the same as or different from each other and each independently indicates an optionally substituted C3-8 cycloalkyl group, an optionally substituted C3-8 cycloalkenyl group, an optionally substituted 5 to 14-membered non-aromatic heterocyclic group selected from the group consisting of pyrrolidinyl groups, piperidinyl groups, piperazinyl groups, and morpholinyl groups, an optionally substituted C6-14 aromatic hydrocarbocyclic group selected from the group consisting of phenyl groups and naphthyl groups, an optionally substituted 5 to 14-membered aromatic heterocyclic group selected from the group consisting of pyrrolyl groups, pyridyl groups, pyrimidinyl groups, pyraziny groups, thienyl groups, thiazolyl groups, furyl groups, guinolyl groups, isoquinolyl groups, indolyl groups, benzimidazolyl groups, benzothiazolyl groups, benzoxazolyl groups, imidazopyridyl groups, carbazolyl groups, and dioxinyl groups, or an adamantyl group; and
R17 and R18 are the same as or different from each other and each independently indicates a hydrogen atom, a halogen atom or a C1-6 alkyl group, or a salt thereof.
