摘要:
5,5-Dialkyl-3-pyrroline-2,2-dicarboxylic acid esters, useful as plant fungicides and anti-inflammatory agents, are prepared either by reacting an ethynylalkylamine with a bromomalonic ester or by heating a 2-amino-2-allenylmalonic ester with copper metal.
摘要:
PYRROLINE DERIVATIVES OF THE FORMULA: WHEREIN R AND R'' ARE THE SAME OR DIFFERENT AND EACH REPRESENTS A HYDROGEN ATOM OR AN ALKYL GROUP CONTAINING 1 TO 5 CARBON ATOMS (PREFERABLY METHYL), AND THE BENZENE RING IS UNSUBSTITUTED OR CARRIES ONE OR MORE SUBSITUENTS SELECTED FORM HALOGEN ATOMS, ALKYL AND ALKOXY GROUPS CONTAINING 1 TO 5 CARBON ATOMS, AND GYDROXY, NITRO AND AMINO GROUPS, AND THEIR ACID ADDITION SALS, POSSESS PHARMACODYNAMIC PROPERTIES. THEY ACT ON THE CENTRAL NERVOUS SYSTEM, AND ARE ESPECIALLY USEFUL AS ANTI-DEPRESSANTS; FURTHERMORE, THEY SHOW A HYPERTENSIVE EFFECT.
摘要:
Antibacterial 2-ethyl-1-pyrroline-3-carboxamides and derivatives thereof are prepared from either 1-(2-propynyl)-2-pyrrolidinone or 1-(1,2-propadienyl)-2-pyrrolidinone and amines in the presence of base. The carboxamides react with phenyl isocyanates to produce 1-phenylcarbamyl-2-ethyl-2-pyrroline-3-carboxamides, with either an acid halide or acid anhydride to give the corresponding 1-acyl-2-ethylidenepyrrolidine-3-carboxamides and with hydrogen to give the corresponding 2-ethyl-pyrrolidine-3-carboxamides.
摘要:
The present invention provides methodology for carbon-nitrogen bond formation via vinyl or aryl amination. In the process of the invention, an sp2 hybridized radical is reacted with an azomethine moiety to form pyrrolidine and indole compounds. The methodology provides a facile process for the synthesis of compounds having the pyrrolidine or indole subunit and is especially advantageous for compounds having acid or base labile functional groups andor is comprised of chiral centers susceptible to acidbase epimerization.
摘要:
The present invention relates to urethanes and the thio and dithio analogues thereof of general formula 1 wherein m, n, A, X, Y and R1 to R8 are defined as in claim 1, the enantiomers, diastereomers and the salts thereof, particularly the physiologically acceptable acid addition salts thereof which have valuable properties, particularly an inhibitory effect on cholesterol biosynthesis, pharmaceutical compositions containing these compounds, their use and processes for preparing them.
摘要:
ANTIBACTERIAL 2 - ETHYL-1-PYRROLINE-3-CARBOXAMIDES AND DERIVATIVES THEREOF ARE PREPARED FROM EITHER 1-(2-PROPYNYL)-2-PYRROLIDINONE OR 1-(1,2-PROPADIENYL)-2-PYRROLIDINONE AND AMINES IN THE PRESENCE OF BASE. THE CARBOXAMIDES REACT WITH PHENYL ISOCYANATES TO PRODUCE 1-PHENYLCARBAMYL-2-ETHYL-2-PYRROLINE-3-CARBOXAMIDES, WITH EITHER AN ACID HALIDE OR ACID ANHYDRIDE TO GIVE THE CORRESPONDING 1-ACYL - 2 - ETHYLIDENEPYRROLIDINE-3-CARBOXAMIDES AND WITH HYDROGEN TO GIVE THE CORRESPONDING 2-ETHYL-PYRROLIDINE-3-CARBOXAMIDES.
摘要:
GUANIDINO OR UREIDO OR THIOUREIDO PYRROLINES (A) PREPARED FROM 2-AMINO-$1-PYRROLINES. (B). BOTH (A) AND (B) LOWER THE BLOOD SUGAR CONTENT IN WARM BLOODED ANIMALS; HENCE, ARE USEFUL AS HYPOLGLYCEMIC AGENTS.
摘要:
