Retrosynthesis is a strategy to analyze the synthetic routes for target molecules in medicinal chemistry. However, traditional retrosynthesis predictions performed by chemists and rule-based expert systems struggle to adapt to the vast chemical space of real-world scenarios. Artificial intelligence (AI) has revolutionized retrosynthesis prediction in recent decades, significantly increasing the accuracy and diversity of predictions for target compounds.

Tris(pentafluorophenyl)borane B(CF)·HO is reported as a catalyst for dehydrative amidation of carboxylic acids and amines. This protocol is applicable across a wide range of >35 substrates, including aromatic and aliphatic amines and acids, resulting in amides in ≤92% yields. The scalability of the reaction up to 10 mmol, along with the synthesis of drugs such as ibuprofen amide, moclobemide, and phenacetin, demonstrates the industrial potential of our protocol.

An effective approach for the immobilization and protection of biological entities is their encapsulation via the in situ synthesis of metal-organic frameworks (MOFs). To ensure the preservation of the bioentities, mild synthetic conditions, including aqueous media and ambient conditions (temperature and pressure), are preferred. In this study, we investigated the synthesis of various aluminum polycarboxylate-based MOFs, including the fumarate, terephthalate, amino-terephthalate, and muconate forms of MIL-53(Al), as well as the MIL-110 and MIL-160 MOF types.

In this work, we present a photoredox three-component reaction that enables the synthesis of medicinally relevant β-trifluoromethyl β-amino ketones from a -trifluoroethylhydroxylamine derivative, styrenes and DMSO. Remarkably, fluoromethyl, difluoromethyl and pentafluoroethyl analogues are also accessed using the same reaction conditions. The mechanistic investigations, including radical trapping experiments, cyclic voltammetry, Stern-Volmer quenching studies and isotope labelling experiments support the photoinduced radical/polar crossover and Kornblum-type oxidation mechanisms.
