Изобретение относитс к способу получени новых фосфорорганических соединений, которые могут найти применение в качестве полупродуктов синтеза биологически активных веществ, а также присадок к маслам.The invention relates to a method for producing new organophosphorus compounds that can be used as intermediates for the synthesis of biologically active substances, as well as additives to oils.
Известны тиаазафосфоланы, незамещенные в третьем и четвертом положении или замещенные в третьем иоложении алкильной группой .Known are thiazaphospholanes, unsubstituted in the third and fourth position, or substituted in the third grade by an alkyl group.
Из числа соединений подобного типа, в которых азот цикла был бы соединен с карбонильной группой, известны лишь полученные недавно 2-диалкиламино - 3 - ацил-1,3,2-оксаазафосфоланы , которые получают взаимодействием гексаэтилтриамида фосфористой кисЛОТЫ с «-ацетиламиноэтанолом.Among the compounds of this type in which the nitrogen of the cycle would be combined with a carbonyl group, only recently obtained 2-dialkylamino-3-acyl-1,3,2-oxa-azaphospholanes are obtained, which are obtained by the interaction of hexaethyl triamide phosphorous acid with α-acetylaminoethanol.
Принципиальное отличие соединений заключаетс в том, что в этих соединени х карбонил , св занный с азотом, находитс в боковой цени, тогда как в соедииени х, нолучаемых по предлагаемому методу, карбонильна группа включена в цикл.The principal difference between the compounds is that in these compounds the carbonyl bonded to nitrogen is in the lateral value, whereas in compounds obtained by the proposed method, the carbonyl group is included in the cycle.
Таким образом получены соединени новой неизвестной ранее структуры одновременной реакцией меркаптолиза и переамидировани амидофосфатов, котора ранее дл амидов КИСЛОТ трехвалентного фосфора не была известна .In this way, compounds of a previously unknown previously obtained structure were obtained by the simultaneous reaction of mercaptolysis and transamidation of amidophosphates, which previously was not known for trihydric phosphorus amides.
Согласно изобретению, описываетс способ получеии 2-диалкиламино-3-арил-4-от-ссо-1, 3, According to the invention, a process for the preparation of 2-dialkylamino-3-aryl-4-ot-cso-1, 3 is described,

Предлагаемый способ позвол ет получать фосфорсодержащие гетероциклы, содержащие в четвертом положении оксогруппу, следующего строени The proposed method allows to obtain phosphorus-containing heterocycles containing an oxo group in the fourth position, the following structure

Процесс ведут при повыщенной температуре 100-130° С с последующим выделением целевого продукта известными приемами.The process is carried out at an elevated temperature of 100-130 ° C, followed by separation of the target product by known techniques.
При м е р. Эквимол рные количества гексаалкилтриамида фосфористой кислоты и моноариламида тиогликолевой кислоты нагревают при перемешивании и 100-130° С с одновременной отгонкой выдел ющегос диалкиламина . Нагревание ведут до тех пор, пока не отгонитс около 75% расчетного количества диалкиламина (из расчета 2 мол диалкиламина на 1 моль вз того в реакцию гексаалкилтриамидофосфита ), удал ют в вакуумеAn example. Equimolar amounts of hexaalkyltriamide of phosphorous acid and thioglycolic acid monoarylamide are heated with stirring at 100-130 ° C with simultaneous distillation of the liberated dialkylamine. Heating is carried out until about 75% of the calculated amount of dialkylamine is distilled off (at the rate of 2 mol of dialkylamine per 1 mol of hexaalkyltriamidophosphite reacted), removed in vacuum
остатки диалкиламина и оставшуюс массу фракционируют.the dialkylamine residues and the remaining mass are fractionated.
Из 12,35 г гексаэтилтриамида фосфористой кислоты и 8,35 г анилида тиогликолевой кислоты получают 8,5 г (63,4%) 2-диэтиламино-Зфеиил-4-оксо-1 ,3,2 - тиаазафосфолана. Т. кип. 99--10ГС (0,015); т. пл. 43-45°С.From 12.35 g of phosphorous acid hexaethyl triamide and 8.35 g of thioglycolic anilide anhydride, 8.5 g (63.4%) of 2-diethylamino-Cfeiyl-4-oxo-1, 3,2-thiaazaphospholane are obtained.
