Nitrogen Nucleophiles: A general method for direct N-acylation of less nucleophilic nitrogen heterocycles with carboxylic acids is reported. The method, which uses simple, commercially available reagents, no metals and user-friendly conditions, shows excellent functional group tolerance and broad substrate scope for both nitrogen nucleophiles and carboxylic acids.

A robust allylic palladium-NHC complex was developed and exhibited extremely high catalytic activity toward aminocarbonylation of various (hetero)aryl iodides under atmospheric carbon monoxide pressure, in which a broad range of secondary and primary amines were well tolerated. In addition, the concise synthesis of an anticancer drug tamibarotene was accomplished even in a gram scale, further highlighting the practical applicability of the protocol.

There is provided a molecularly imprinted polymer (MIP) comprising an anchoring group which could covalently bond to a sensing substrate for better adhesion of the MIP to the sensor substrate, the anchoring group comprising at least one of: cyclic imide, O-acylisourea, azide, carboxylic acid, amine, hydroxyl, or thiol. There is also provided a method of making the MIP comprising the anchoring group.
