Abstract
1. Способ получения метил 1,7-диарил-9-ароил-4-бензоил-3-гидрокси-2,6-диоксо-1,7-диазаспиро[4.4]нон-3,8-диен-8-карбоксилатов общей формулы:где Ar- CHMe-4, Ar- Ph, Ar- CHMe-4 (IIIa), Ar- СНМе-4, Ar- CHCl-4, Ar- CHMe-4 (IIIб), Ar- CHMe-4, Ar- CH, Ar-.CHCl-4 (IIIв), Ar- CHOEt-4, Ar2 - Ph, Ar- CHOEt-4 (IIIг), отличающийся тем, что путем кипячения 1-арил-4-бензоил-5-метоксикарбонил-1H-пиррол-2,3-дионы (Ia,б) подвергают взаимодействию с метил 4-арил-2-ариламино-4-оксо-2-бутеноатами (IIa-г), взятыми в соотношении 1:1 в среде инертного апротонного растворителя с последующим выделением целевых продуктов.2. Способ по п.1 отличающийся тем, что в качестве растворителя используют абсолютный толуол.1. The method of obtaining methyl 1,7-diaryl-9-aroyl-4-benzoyl-3-hydroxy-2,6-dioxo-1,7-diazaspiro [4.4] non-3,8-diene-8-carboxylates of the General formula : where Ar-CHMe-4, Ar-Ph, Ar-CHMe-4 (IIIa), Ar-CHMe-4, Ar-CHCl-4, Ar-CHMe-4 (IIIb), Ar-CHMe-4, Ar- CH, Ar-.CHCl-4 (IIIc), Ar-CHOEt-4, Ar2-Ph, Ar-CHOEt-4 (IIIg), characterized in that by boiling 1-aryl-4-benzoyl-5-methoxycarbonyl-1H -pyrrole-2,3-diones (Ia, b) are reacted with methyl 4-aryl-2-arylamino-4-oxo-2-butenoates (IIa-g) taken in a 1: 1 ratio in an inert aprotic solvent with subsequent isolation of target products. 2. The method according to claim 1, characterized in that absolute toluene is used as the solvent.
