The present invention relates to novel heterocyclicalkyl derivatives having histone deacetylase (HDAC) inhibitory activity, optical isomers thereof or pharmaceutically acceptable salts thereof, the use thereof for the preparation of medicaments, pharmaceutical compositions containing the same, a method for treating diseases using the composition, and methods for preparing the novel heterocyclicalkyl derivatives. The novel heterocyclicalkyl derivatives according to the present invention are selective histone deacetylase (HDAC) inhibitors, and may be effectively used for the treatment of histone deacetylase-mediated diseases, such as cell proliferative diseases, inflammatory diseases, autosomal dominant diseases, genetic metabolic diseases, autoimmune diseases, acute/chronic neurological disease, hypertrophy, heart failure, ocular diseases, or neurodegenerative diseases.
A heterocyclic compound useful as an antiallergic agent is provided.
A compound represented by the following formula (1) or a salt thereof:
wherein the ring A is a homocyclic or heterocyclic ring; the ring B is a heterocyclic ring which contains G and nitrogen atom N as constituent atoms thereof, wherein G is CH or N; R
1
is a carbonyl group or an alkylene group; R
2a
and R
2b
are an alkyl group, a cycloalkyl group, an aryl group, or a heterocyclic group; X is an oxygen atom or a sulfur atom; Z is a hydroxyl group, an alkoxy group, a cycloalkyloxy group, an aryloxy group, an aralkyloxy group, an amino group, or an N-substituted amino group; and n is 0 or 1; with the proviso that when the ring A is a benzene ring or when the ring B is a piperazine ring, R
1
is an alkylene group which may have a substituent.

positioned electron-withdrawing groups to activate the aromatic rings toward addition by nucleophilic amines. While 2,2′difluorobenzophenone could potentially undergo such a reaction, it was expected that further activation would be necessary. The easiest activatinggroup to introduce to this system is the nitro function. This could be added by electrophilic aromatic substitution and would be expected to

The borylation of C−Hbonds catalyzed by transition metals has been investigated extensively in the past two decades, but no iridium‐catalyzed enantioselectiveborylation of C−Hbonds has been reported. We report a set of iridium‐catalyzed enantioselectiveborylations of aromaticC−Hbonds. This reaction relies on a set of newly developed chiral quinolyl oxazoline ligands. This process proceeds under
An efficient method for the highly regio‐ and stereoselective synthesis of 1,2,3‐trisubstituted indanes from diarylmethanols and allylamides through iron(III) chloride hexahydrate‐catalyzed intermolecular [3+2] cycloaddition reaction is reported. A range of 1,2,3‐trisubstituted indanes were prepared in good to excellent yields with excellent stereoselectivities for various combinations of diarylmethanols
