    The title compound, C39H37NO8, is a product of the Michael addition of the cyclic secondary amine subunit of aza-14-crown-4 ether to dimethyl acetylΒ­enedicarboxylΒ­ate. The piperidinone ring exhibits a distorted chair conformation and the dimethyl acetylΒ­enedicarboxylΒ­ate fragment has a cis configuration with a dihedral angle of 56.61β€…(5)Β° between the two carboxylΒ­ate groups. The crystal packing is stabilized by the weak Cβ€”Hβ‹―O hydrogen bonds

    Recently, in the scientist community of specialists dealing with structural epilepsy, it has been noticed an increasing interest in a special form of cortical development disorder not to be included in the ILAE Classification of the epilepsies the 2017 revision. It is so-called mild malformation of cortical development with oligodendroglial hyperplasia and epilepsy (MOGHE). There are a number of publications devoted to the neuroimaging features of MOGHE, which are possible to distinguish from other epileptogenic substrates in comparisons with clinical/anamnestic data and dynamic observation. Our paper describes the case of a patient under 6 years suffering from pharmacoresistant epilepsy with histologically confirmed MOGHE, and having undergone the procedure of epileptic surgery. MRI showed an increased intensity of the T2/FLAIR signal from the white matter in combination with signs of laminar hyperintensivity, regional sulcation disturbance, smoothness of gray-white matter demarcation in the right frontal lobe. A signal intensification from the white matter with the formation similarity of the Β«transmantlΒ» sign and further pronounced smoothness of the gray-white matter demarcation was observed on dynamic MRI. These changes were estimated as focal cortical dysplasia. Pre-surgical examination revealed a correlation of epileptiform activity with MRI changes. The subtotal resection of the right frontal lobe and the morphological conclusion established the presence of MOGHE was performed.Π’ послСднСС врСмя Π² Π½Π°ΡƒΡ‡Π½ΠΎΠΌ сообщСствС спСциалистов, Π·Π°Π½ΠΈΠΌΠ°ΡŽΡ‰ΠΈΡ…ΡΡ структурной эпилСпсиСй, возрастаСт интСрСс ΠΊ особой, Π½Π΅ входящСй Π² ΠΊΠ»Π°ΡΡΠΈΡ„ΠΈΠΊΠ°Ρ†ΠΈΡŽ ILAE послСднСго пСрСсмотра 2017 Π³., Ρ„ΠΎΡ€ΠΌΠ΅ Π½Π°Ρ€ΡƒΡˆΠ΅Π½ΠΈΡ ΠΊΠΎΡ€ΠΊΠΎΠ²ΠΎΠ³ΠΎ развития β€” Ρ‚Π°ΠΊ Π½Π°Π·Ρ‹Π²Π°Π΅ΠΌΠΎΠΉ ΡƒΠΌΠ΅Ρ€Π΅Π½Π½ΠΎΠΉ ΠΌΠ°Π»ΡŒΡ„ΠΎΡ€ΠΌΠ°Ρ†ΠΈΠΈ ΠΊΠΎΡ€ΠΊΠΎΠ²ΠΎΠ³ΠΎ развития с ΠΎΠ»ΠΈΠ³ΠΎΠ΄Π΅Π½Π΄Ρ€ΠΎΠ³Π»ΠΈΠ°Π»ΡŒΠ½ΠΎΠΉ Π³ΠΈΠΏΠ΅Ρ€ΠΏΠ»Π°Π·ΠΈΠ΅ΠΉ ΠΈ эпилСпсиСй (MOGHE).
