Synthesis of substituted [8]cycloparaphenylenes by [2 + 2 + 2] cycloaddition

A new modular approach to the smallest substituted cycloparaphenylenes (CPPs) is presented. This versatile method permits access to substituted CPPs, choosing the substituent at a late stage of the synthesis. Variously substituted [8]CPPs have been synthesized, and their properties analyzed. The structural characteristics of substituted CPPs are close to those of unsubstituted CPPs. However, their optoelectronic behavior differs remarkably due to the larger torsion angle between the phenyl units.

NOVEL HETEROCYCLIC AMIDE DERIVATIVES HAVING DIHYDROOROTATE DEHYDROGENASE INHIBITING ACTIVITY

Novel heterocyclic amide derivatives having pharmacological effects, that is, compounds represented by the general formula (1) or salts thereof: (1) wherein X1-X2 is S-CH2 or the like; R1 is alkyl or the like; p is 0 to 7; R2 is hydrogen, alkyl, or the like; R3 is hydrogen, alkyl, or the like; Y1-Y2 is CH=CH or the like; R4 is halogeno, alkyl, or the like; q is 0 to 4; and R5 is halogeno, hydrogen, alkyl, or the like.

Phenethanolamine compounds

The invention provides compounds of the general formula (I) STR1 wherein the substituents are defined in the specification, and physiologically acceptable salts and solvates thereof. The compounds of formula (I) have a selective stimulant action at β2 -adrenoreceptors and are useful, in particular in the treatment of diseases associated with reversible airways obstruction such as asthma and chronic bronchitis.
