(5«) СПОСОБ ПОЛУЧЕНИЯ 1 ,5-ДИФЕНИЛ-2-н-БУТИЛТИОМЕТИЛЕНПЕНТАНДИОНА-1,5(5 ") METHOD OF OBTAINING 1, 5-DIPHENYL-2-n-BUTYL-THIOMYLENE PENTANDION-1,5
Изобретение относитс к новому способу получени нового производного 1,5-ДИкетон, конкретно к способу получени 1,5-ДИфенил-2-Н-бутилтиометиленпентандиона-1 ,5 формулыThe invention relates to a new method for producing a new derivative 1,5-Dicetone, specifically to a method for producing 1,5-Diphenyl-2-H-butylthiomethylenepentanedione-1, 5 of formula
который может найти применение в синтезе биологически активных соединений ..which can be used in the synthesis of biologically active compounds ..
Известен способ получени метиленаминопроизводных 1,5 дикетонов формулыA known method for producing methyleneamino derivatives of 1.5 diketones of the formula
ХX
где X - атом водорода или фенил; X - этил, или оба XI вместе с атомом азота образуют пиперидиновое кольцо, или оба X вместе с атомом азота и атомом кислорода образуют морфолиновое кольцо, который заключаетс в том, что метилен- или бензилиден-диацетофенон подвергают взаимодействию с диалкил10 амином формулыwhere X is a hydrogen atom or phenyl; X is ethyl, or both XI together with the nitrogen atom form a piperidine ring, or both X together with the nitrogen atom and the oxygen atom form a morpholine ring, which is that the methylene or benzylidene diacetophenone is reacted with a dialkyl 10 amine of the formula
