Lacosamide has been submitted for regulatory approval in the United States and Europe for the treatment of epilepsy. Previous synthetic methods did not permit the elaboration of the structure-activity relationship (SAR) for the 3-oxy site in lacosamide. We report an expedient five-step stereospecific synthesis for N-benzyl (2R)-2-acetamido-3-oxysubstituted propionamide analogs beginning with d-serine methyl ester. The procedure incorporated alkyl (e.g. methyl, primary, secondary, and tertiary) and aryl groups at this position. The SAR for the 3-oxy site showed maximal activity in animal seizure models for small 3-alkoxy substituents.

In a patent, introducing its new discovery.

Chilecomadia valdiviana (Philippi) (Lepidoptera: Cossidae) is an insect native to Chile. The larval stages feed on the wood of economically important fruit tree species such as apple, pear, olive, cherry, and avocado, and also on eucalyptus. This causes weakening and, in case of severe infestation, death of the tree. We report identification of the sex pheromone produced by females of this species. Hexane extracts of the abdominal glands of virgin females were analyzed by gas chromatography (GC) with electroantennographic detection, GC coupled with mass spectrometry, and GC coupled to infrared spectroscopy. The major pheromone component was identified as (7Z,10Z)-7,10-hexadecadienal (Z7,Z10?16:Ald), and minor components present in the extracts were (Z)-7-hexadecenal and (Z)-9-hexadecenal, hexadecanal, and (9Z,12Z)-9,12-octadecadienal. Structural assignments were carried out by comparison of analytical data of the natural products and their dimethyl disulfide adducts with those of authentic reference samples. In field tests, traps baited with Z7,Z10?16:Ald captured significantly more males than control traps.

On the basis of amino derivatives of N-phenylnaphthalimide, naphthoylenebenzimidazole, benzanthrone, and phenalenone new phosphorus-containing luminophores containing phosphonomethyl and phosphazo groups in their structures were synthesized. Luminiscence spectrum and excitation characteristics of compounds obtained were studied. Some of the synthesized substances were proposed for application as effective laser dyes for green and red spectral regions with a wide range of retuning.

Several derivatives of the pyrido[1?,2?:1,2]pyrimido[4,5-b]indoles 4 and the pyrazino[1?,2?:1,2]-pyrimido[4,5-b]indoles 14 were synthesized by treatment of the benzannulated enyne-isocyanates 8 with the iminophosphoranes 9 and 13, respectively, for the aza-Wittig reaction followed by thermolysis. The reaction presumably proceeds through an initial formation of the corresponding benzannulated enyne-carbodiimides, such as 10, followed by a formal intramolecular hetero Diels-Alder reaction. Surprisingly, when the iminophosphorane 17 was used for condensation with 8, the expected pyrimido[1?,6?:1,2]pyrimido[4,5-b]indoles 16 were not obtained. Instead, the isomeric pyrimido[6?,1?:2,3]pyrimido[4,5-b]indoles 21 were isolated. Presumably, an alternative reaction pathway involving an initial [2 + 2] cycloaddition reaction to form 19 followed by ring opening could lead to 20 and, after an intramolecular radical-radical coupling, 21. Treatment of the urea derivatives 24 with dibromotriphenylphosphorane also produced in situ the benzannulated enynecarbodiimides 25, which on thermolysis gave the isoquinolino[2?,1?:1,2]pyrimido[4,5-b]indoles 26. Methylation of 4a, 14a, and 26a with methyl iodide occurred exclusively at the site of the indolo nitrogen. The planar geometry of those novel heteroaromatic compounds, resembling many DNA-binding agents, makes them potential candidates as DNA intercalators.

A spheroidal bis-porphyrin (dual capped quadruply cofacial dimeric tetraphenylporphyrin, 1), designed to be employed as a ligand for a class of catalysts that mimic the combined enzyme activities of superoxide dismutase and catalase, has been synthesized in 9 steps.C-Alkylation of 2-(2′-lithio-5′-tert-butyldimethylsiloxy-methyl)phenyl-1,3-dioxolane (D) with tetra-bromide 6, prepared from bicyclo<2.2.2>oct-7-ene-2,3,5,6-tetracarboxylic dianhydride by 5 steps, afforded the key intermediate, tetra-alkylated compound 3a, in 66percent yield.An alternative route to 3, O-alkylations of tetrol 4 with aliphatic halides 5, was also tested.Conversion of the four protected hydroxy groups to bromo substituents is crucial in the preparation of porphyrin 2.Therefore, tetra-benzyl bromide 24b was prepared and then treated with pyrrole in the presence of boron trifluoride etherate, followed by DDQ oxidation to obtain the capped porphyrin 2.The coupling of two molecules of 2 to form a spheroidal porphyrin 1 was carried out in dilute DMF solution, using 0.8 equivalent of 2-trimethylsilylethane sulfonamide (H2NSO2CH2CH2Si(CH3)3, SES-NH2) and cesium carbonate.The structure of 1 was confirmed by 1H NMR, UV/VIS, FABMS and laser desorption high resolution MS.The two isomers of 1, eclipsed and gauche, formed due to two possible modes of approach of the units of 2, were observed in approximately 1:1 ratio by both 1H NMR and HPLC techniques.
