摘要:
The application relates to a process for preparing (3,3-difluorocyclobutyl)isonitrile of formula (2) comprising the steps of mixing N-(3,3-difluorocyclobutyl)formamide with an aprotic solvent and reacting the N-(3,3-difluorocyclobutyl)formamide with propylphosphonic acid anhydride in the presence of a tertiary amine base. The intermediate of formula (2) is used for the preparation of ivosidenib of formula (4).
摘要:
The invention relates to new amino-isocyanonaphthalene compound, which are solvatochromic fluorophores. Their fluorescent properties were investigated in detail by steady-state and time dependent methods.

Disclosed are novel compounds represented by structural Formula (XX), (XXI) or (XXII); R1, R21 and R22 are independently an aliphatic group, a substituted aliphatic group, an aromatic group or a substituted aromatic group. R2 and R12 are independently -NR4R5 or -N?+ C-. R¿3 is -H or an alcohol protecting group. R4 and R5 are independently -H or an amine protecting group. R11 is a side chain of a naturally occurring amino acid or a protected side chain of a naturally occurring amino acid. R1 and R2, and R11 and R12, taken together with the methine group to which they are bonded, can form a moiety represented by structural Formula (XXIII). R6 is -H or an amine protecting group. R7 is -H, -OH or -OR8. R8 is an alcohol protecting group. Also disclosed are methods of preparing these compounds.
摘要:
A composition comprising the following structure: (1) wherein Re represents a rhenium ion having a +1 charge; (I) represents an uncharged bidentate ligand containing at least one ring containing a ring nitrogen atom bound to the rhenium (Re), and the bidentate ligand containing another nitrogen atom, either in a ring or not in a ring, bound to the rhenium (Re); and L 1 , L 2 , L 3 , and L 4 are neutral ligands with at least one neutral ligand being an isonitrile ligand of the formula -CN-R, wherein R is an aliphatic or aromatic hydrocarbon group containing 1-20 carbon atoms; and X - represents a non-coordinating monovalent anion; wherein the bidentate ligand and R are optionally substituted by one or more groups selected from (i)-(xi) as further discussed above. Methods for treating a condition that benefits from ER stress induction, such as cancer, by administering the above rhenium complex are also disclosed.
摘要:
The present invention relates to new synthetic methods for preparing 2- methoxyisobutylisonitrile and metal isonitrile complexes, such as tetrakis(2- methoxyisobutylisonitrile)copper(I) tetrafluroroborate, which are used in the preparation of technetium ( 99m Tc) Sestamibi, and novel intermediate compounds useful in such methods.
摘要:
The invention relates to methods for preventing the attachment of aquatic organisms to surfaces that are submerged for extensive periods of time in water. More particularly, this invention relates to the protection of submerged surfaces with alkylamine derivatives as antifouling agents. The invention is beneficiary for the environment in that it will permit the use of copper- and tin-free paints.
