摘要:
N-MONO- AND N,N''-DIOXIDES OF DIALKOXYPHENAZINES ARE PREPARED BY OXIDATION OF THE APPROPRIATE DIALKOXYPHENAZINES. THE CORRESPONDING MONO- AND DI-HYDROXYALKOXYPHENAZINES ARE PREPARED BY SELECTIVE ETHER CLEAVAGE OF THE DIALKOXY COMPOUNDS OR BY SELECTIVE MONO-OR DI-ALKYLATION OF THE DIHYDROXY OR PROTECTED MONO-HYDROXY COMPOUNDS. THE PHENAZINE N,N''-DIOXIDES POSSESS USEFUL ANTIMICROBIAL PROPERTIES.
摘要:
Ortho-nitrotoluenes are condensed with formamide acetals to yield the corresponding ortho-nitro- Beta -aminostyrenes which undergo cyclization upon reduction to yield indoles.
摘要:
Secondary Alpha -amino acids are fluorometrically assayed by conversion to primary amines followed by reaction with known fluorogenic reagents and measurement of fluorescence. This technique is suitably adapted for automated analysis.
摘要:
A NOVEL CLASS OF REAGENTS REACT WITH PRIMARY AMINECONTAINING COMPOUNDS, PREFERABLY POLYPEPTIDES AND AMINO ACIDS, TO FORM HIGHLY FLUORESCENT PRODUCTS. THIS REACTION SERVES AS A BASIS FOR A RAPID AND HIGHLY SENSITIVE ASSAY METHOD FRO PRIMARY AMINE-CONTAINING COMPOUNDS.
摘要:
Pharmaceutical compositions containing, as the active ingredient, copper derivatives of 6-lower alkoxy-1-phenazinol 5,10-dioxide and, in particular, the copper II complex of 6methoxy-1-phenazinol 5,10-dioxide, possess broad spectrum antimicrobial activity.
WHEREIN R'' IS LOWER ALKYL OR ARYL, USEFUL AS INTERMEDIATES FOR FLUOROMETRIC REAGENTS, COMPRISING CONDENSATION OF 1,3-INDANDIONE WITH A LOWER ALKYL OR ARYL ALDEHYDE, EXOXIDATION AND BASIC CLEAVAGE.
摘要:
THIS INVENTION IS DIRECTED TO A PROCESS FOR THE PREPARATION OF MALONONITRILE AND CYANOACETAMIDE FROM THE REACTION PRODUCT OF A DIALKYL ACETAL OF A DIALKYL FORMAMIDE AND ACETONITRILE INCLUDING INTERMEDIATES THEREIN.
摘要:
THIS INVENTION IS DIRECTED TO A PROCESS FOR THE PREPARATION OF 4-AMINO-2-METHYLPYRIMIDINE 5-CARBOXAMINE FROM 2-CYANO-3-DI(LOWER ALKYL)AMINO ACROLEIN. THE 4-AMINO2-METHYLPYRIMIDINE 5-CARBOXAMIDE IS A KNOWN COMPOUND WHICH IS A VALUABLE INTERMEDIATE IN THE SYNTHESIS OF THIAMINE.
摘要:
This invention is directed to a process for the preparation of aminomethylene malononitrile from dialkyl aminoacylonitrile including intermediates therein. Aminomethylene malononitrile is a known compound which is a valuable intermediate in the synthesis of thiamine.
