摘要:The present invention relates to 8-aryl-substituted and 8-heteroaryl-substituted 9H-pyrido[3,4-b]indoles of the formula (I), in which A, E, G, R1 to R6 and R10 are as defined in the claims, which stimulate chondrogenesis and cartilage matrix synthesis and can be used in the treatment of cartilage disorders and conditions in which a regeneration of damaged cartilage is desired, for example joint diseases such as osteoarthritis. The invention furthermore relates to processes for the synthesis of the compounds of the formula (I), their use as pharmaceuticals, and pharmaceutical compositions comprising them.

摘要:Provided is a process for the preparation of certain 1,4-bicyclo[2.2.2]octane derivatives. The new synthetic procedure involves treating 1,4-dimethylene cyclohexane with an oxidizing agent in the presence of a transition metal catalyst to afford an oxo-substituted bicyclo[2.2.2]octane species. This intermediate structure can then be further derivatized. The processes of this disclosure thus affords a novel and simplified means for the commercial production of a wide variety of bicyclo[2.2.2]octane derivatives.

摘要:A process for making the compound of formula (I) n nwherein Ac represents acetate; X represents O or CH 2 ; Y represents C 1 -C 6 alkyl; and Z is selected from the group consisting of H, halogen, CN, CHO, CF 3 , OCF 3 , OH, C 1 -C 6 alkyl, C 1 -C 6 alkoxy, C 1 -C 6 thioalkyl, NH 2 , N(C 1 -C 6 alkyl) 2 , NH(C 1 -C 6 alkyl), NC(O)—(C 1 C 6 alkyl), and NO 2 . In his process, a compound of formula (II)n n nis reacted with hydrazine to form a primary alkylamine, and then the primary alkylamine is reacted with acetic anhydride, to produce the compound of formula (I).

标题 :Synthesis of 3,3,-dimethylbutyraldehyde by the reduction of 3,3,-dimethylbutyric acid
发明人：PRAKASH INDRA; AUGUSTINE ROBERT L; TANIELYAN SETRAK K
权利人:NUTRASWEET CO
摘要:A process for the production of 3,3-dimethylbutyraldehyde is disclosed. The 3,3-dimethylbutyraldehyde is obtained by the reduction of 3,3-dimethylbutyric acid using trimethylacetic anhydride and a phosphine. The 3,3-dimethylbutyric acid is preferably obtained by a process in which tert-butanol and vinylidene chloride are reacted in the presence of sulfuric acid. The disclosed process has improved cost and yield.
