Benzopiperidine derivatives represented by formula (I), salts thereof or hydrates thereof, processes for producing the same and drugs comprising the same:
wherein the variables are as described in the specification. These compounds are useful as drugs efficacious in the prevention and treatment of these various inflammatory diseases and immunologic diseases, such as rheumatoid arthritis, atopic dermatitis, psoriasis, asthma, and rejection reaction accompanying organ transplantation.
This invention provides a benzopiperidine derivative represented by the following general formula (I), its salt or hydrates thereof:
wherein R1 to R3 may be the same or different and each represents hydrogen, optionally substituted lower alkyl, optionally substituted lower cycloalkyl or the like, provided that the case where R1 to R3 each represents methyl in the case of lower alkyl is excluded; R represents hydrogen, lower alkyl or the like; E represents N, C or the like; Z represents O, S, SO, SO2 or the like; and the ring G represents an optionally substituted heteroaryl ring having one or more nitrogen atoms. Those are effectively used for a drug for preventing or remedying inflammatory immunologic diseases and autoimmune diseases, or a drug for preventing or remedying rheumatism, collagen disease, asthma, nephritis, ischemic reflow disorders, psoriasis, atopic dermatitis or rejection reaction accompanying organ transplantation.
and good to high enantioselectivity. Results show that the enantioselectivity depends on the solvent system and substituents at the 3,3′-position of the catalyst. Thus, the best result can be obtained using a catalyst that has 2,4,6-tricyclohexylphenyl groups at the 3,3′-positions in a mixture of fluorobenzene and n-heptane. In addition, the construction of a quaternary carbon center with the retention
