Abstract: A method for the preparation of the 2-hydroxy-4-methylthiobutyronitrile (HMTBN) or its selenium equivalent (HMSeBN) from hydrocyanic acid and 3-methylthiopropanal (MTP) or the corresponding selenium aldehyde (MSeP) includes the following steps: the molar ratio of the HCN to MTP or to MSeP is adjusted to a value greater than or equal to 1 and the pH is adjusted and maintained at a value greater than or equal to 3.5, to obtain a reaction medium in which the HMTBN or the HMSeBN is formed, then the pH of the reaction medium is lowered to a value less than or equal to 2.5 and the HCN is extracted from the reaction medium, and the HMTBN or the HMSeBN is recovered. The applications of this method are also related.

Abstract: The invention relates to an N-heterocyclic carbene complex of general formulas I to IV (I) (II) (III) (IV), according to which A1 stands for NR2 or PR2, A2 stands for CR2 R2′, NR2, PR2, 0 or S, A3 stands for N or P, and C stands for a carbene carbon atom, ring B is an unsubstituted or a mono or poly-substituted 5 to 7-membered ring, substituents R2 and R2′ stand, inter alia, for a linear or branched C1-Cw-alkyl group and, if N and N each stand for NR2 or PR2, are the same or different, M in formulas I, II, III or IV stands for Cr, Mo or W, X 1 or X2 in formulas I to IV are the same or different and represent, inter alia, C1-C1s carboxylates and C1-C1s-alkoxides, Y is inter alia oxygen or sulphur, Z is inter alia a linear or branched C1-Cw-alkylenoxy group, and R 1 and R1′ in formulas I to IV are, inter alia, an aliphatic or aromatic group. These compounds are particularly suitable for use as catalysts for olefin metathesis reactions and have the advantage, compared to known Schrock carbene complexes, of displaying clearly increased tolerance to functional groups such as, in particular, aldehydes, secondary amines, nitriles, carboxylic acids and alcohols.

Abstract: The present invention provides a compound represented by formula (I), a pharmaceutically acceptable salt thereof or a solvate thereof. (In the formula, each of A and Z independently represents CO, SO or SO2; each of X and Y independently represents S or O; each of R1-R4 independently represents a hydrogen atom, an alkyl group, an alkenyl group, an alkynyl group or a halogen group; each R5 independently represents an alkyl group, an alkenyl group, an alkynyl group or a halogen group; and n represents an integer of 0-4.) This compound is capable of specifically binding to an AMPA receptor, and shows extremely high brain uptake.
