Practical regioselective halogenation of vinylogous esters: Synthesis of differentiated mono-haloresorcinols and polyhalogenated resorcinols

A practical and efficient method for the direct, regioselective conversion of vinylogous esters to haloresorcinols is reported. Control of the reaction conditions enables synthesis of either the 4- or 6-haloresorcinol isomers from a common precursor with excellent regiocontrol and high yield. The generality and functional group tolerance of this novel protocol is demonstrated. The utility of this methodology to access polyhaloresorcinols is also reported. These methods create useful functionalized building blocks for further synthetic applications.

GLUCOCORTICOID RECEPTOR AGONIST COMPRISING NOVEL 1,2,3,4-TETRAHYDROQUINOXALINE DERIVATIVE CONTAINING PHENYL GROUP HAVING SULFONIC ACID ESTER STRUCTURE INTRODUCED THEREIN AS SUBSTITUENT

The object aims to find a novel pharmacological activity of a novel 1,2,3,4-tetrahydroquinoxaline derivative which contains, as a substituent, a phenyl group having a sulfonic acid ester structure introduced therein. A compound represented by general formula (1) or a salt thereof is useful as a glucocorticoid receptor agonist, particularly as a therapeutic agent for diseases against which a glucocorticoid receptor agonist (e.g., a steroid) is believed to be effective, such as inflammatory bone/joint diseases, inflammatory ophthalmic diseases (inflammatory ophthalmic diseases in the anterior or posterior segment of an eye). R1 represents a group represented by general formula (2a), (3a), (4a) or (5a); R2 represents a lower alkyl group which may have a substituent, a lower cycloalkyl group which may have a substituent, or the like; R3 represents a lower alkyl group; R4, R5, R6 or R7 represent a halogen atom, a lower alkyl group which may have a substituent, a hydroxy group, a lower alkoxy group which may have a substituent, or the like; and m, n, p or q represents a number of 0, 1 or 2.

Selective iodination of some phenols, anilines and methoxyarenes by molecular iodine in the presence of 1-butyl-3-methylimidazolium hydrogen sulphate

A simple, mild and regioselective method for the iodination of some phenols, anilines and methoxyarenes by using molecular iodine in presence of 1-butyl-3-methylimidazolium hydrogen sulphate ([bmim]-HSO4) in acetonitrile as solvent is reported. One-pot synthesis, mild reaction conditions, short reaction times and excellent yields of the products are noteworthy.

NOVEL 1,2,3,4-TETRAHYDROQUINOXALINE DERIVATIVE WHICH HAS, AS SUBSTITUENT, PHENYL GROUP HAVING SULFONIC ACID ESTER STRUCTURE OR SULFONIC ACID AMIDE STRUCTURE INTRODUCED THEREIN AND HAS GLUCOCORTICOID RECEPTOR-BINDING ACTIVITY

The compounds represented in general formula (1) or a salt thereof are useful for glucocorticoid receptor modulators. In the formula, R1 represents a lower alkyl group, a lower cycloalkyl group, an aryl group and the like; R2 represents a hydrogen atom, a lower alkyl group and the like; R3 represents a hydrogen atom, a lower alkyl group and the like; R4 and R5 represent a hydrogen atom, a lower alkyl group and the like; R6 represents a hydrogen atom, a lower alkyl group and the like; R7 represents a hydrogen atom, a lower alkyl group, a lower alkenyl group and the like; W represents an oxygen atom, a sulfur atom, NR8 and the like; R8 represents a hydrogen atom, a lower alkyl group and the like; X represents an oxygen atom or a sulfur atom; Y represents a lower alkylene group and the like; Z represents an oxygen atom, a sulfur atom, NR9, OCO or OSO2; R9 represents a hydrogen atom, a lower alkyl group and the like respectively.
