摘要:
The new compounds of the formula ##STR1## in which Acyl is alkylcarbonyl optionally substituted by halogen or aryl, or arylcarbonyl, which is substituted by lower alkoxy, halogen or nitro,R.sup.1 is an alkyl or alkenyl radical, andR.sup.4 is an optionally substituted branched or straight-chain C.sub.1 -C.sub.6 -alkyl radical or a cycloalkyl radical,are produced by reacting a 2-halogenoacetylacrylic acid ester of the formula ##STR2## with an acylthiourea of the formula ##STR3## The reaction can be conducted in aqueous DMF, substantially pure Z-isomer selectively crystallizing out.

摘要:
The invention relates to novel phenoxyphenyl alkanesulphonates, processes for their preparation, their use for producing medicaments for the treatment and/or prophylaxis of diseases, in particular for the treatment of states of pain and neurodegenerative disorders.
摘要:
The cycloalkano-pyridines are prepared by reacting corresponding cycloalkano-pyridine-aldehydes with suitable organometallic compounds or Wittig or Grignard reagents or reacting compounds of the cycloalkano-pyridine alcohols type with suitable bromine compounds, and optionally varying the functional groups accordingly. The cycloalkanopyridines are suitable as active compounds in medicaments, in particular in medicaments for the treatment of hypertipoproteinaemia and arteriosclerosis.

摘要:
(7-APCA) having the formula (I) ##STR1## which is an important synthesis intermediate in the preparation of cephalosporin-like antibiotics, is prepared by treating a compound of the formula (II) ##STR2## in which R.sub.1 and R.sub.2 represent alkyl, aryl and aralkyl radicals, with a strong protonic acid or with a Lewis acid. Compound (II) is prepared by adding triphenylphosphine and alkali metal iodide to a compound of the formula (VI) ##STR3## then reacting with acetaldehyde in base. Compound (VI) is prepared by treating a compound of the formula (VII) ##STR4## with a base in a polar solvent at -70.degree. C. to 0.degree. C. Compound (VII) is prepared by treating a compound of the formula (VIII) ##STR5## with a chlorinating agent in an organic solvent.
