Method for catalytic preparation of medical intermediate 2,4,6-triarylpyrimidine derivative

The invention discloses a method for catalytically preparing a medical intermediate 2,4,6-triarylpyrimidine derivative, and belongs to the technical field of pharmaceutical chemicals. The method comprises the following steps: adding a reaction raw materia

Base-promoted formal [4?+?1+1] annulation of aldehyde, N-benzyl amidine and DMSO toward 2,4,6-triaryl pyrimidines

A base-promoted formal [4 + 1+1] annulation of aldehyde, N-benzyl amidine and DMSO was developed, leading to a series of 2,4,6-triaryl pyrimidines in moderate to good yields. Notably, DMSO served as a methine source, which was activated by base rather than either Lewis acid or electrophile. Molecular O2 was the sole eco-friendly oxidant during this procedure.

ELECTROCHROMIC COMPOUND, ELECTROCHROMIC COMPOSITION, DISPLAY ELEMENT, AND DIMMING ELEMENT

An electrochromic compound, represented by the following general formula (I): where X1 to X4 are each a substituent represented by the following general formula (II), an alkyl group that may contain a functional group, an aromatic hydrocarbon group that may contain a functional group, or a hydrogen atom, and at least two selected from X1 to X4 are the substituents represented by the general formula (II): where R1 to R8 are each independently a hydrogen atom, or a monovalent group that may contain a substituent; B is a substituted or unsubstituted monovalent group that may contain a functional group; A- is a monovalent anion; and m is any of 0 to 3, and R1 to R8, B, and m may each independently be different when a plurality of the substituents represented by the general formula (II) are present.
