A procedure for the continuous flow generation of thiomorpholine in a two-step telescoped format was developed. The key step was the photochemical thiol–ene reaction of cysteamine hydrochloride and vinyl chloride as low-cost starting materials. This reaction could be conducted under highly concentrated (4 M) conditions using a low amount (0.1–0.5 mol %) of 9-fluorenone as the photocatalyst, leading

This article is part of the Biocatalysis: Improving Enzymatic Processes through Protein and Reaction Engineering special issue. Notable developments continue in expanding the enzymatic toolbox available to synthetic chemists and in the widespread use of enzyme engineering to enable the development of highly active, selective, and stable biocatalysts. For example, biocatalysis was recognized through

Preparing phosphorylated peptides with multiple adjacent phosphorylations is synthetically difficult, leads to β-elimination, results in low yields, and is extremely slow. We combined synthetic chemical methodologies with computational studies and engineering approaches to develop a strategy that takes advantage of fast stirring, high temperature, and a very low concentration of 1,8-diazabicyclo[5

This Review examines parts per million (ppm) palladium concentrations in catalytic cross-coupling reactions and their relationship with mole percentage (mol %). Most studies in catalytic cross-coupling chemistry have historically focused on the concentration ratio between (pre)catalyst and the limiting reagent (substrate), expressed as mol %. Several recent papers have outlined the use of “ppm level”

Herein, we report the structure and synthesis of the potent MDM2-p53 inhibitor BI-0282. The complex spirooxindole scaffold bearing four stereocenters embedded in a rigid polycyclic ring-system was effectively prepared on a multi-gram scale in only five synthesis steps employing a three-component 1,3-dipolar cycloaddition and a late-stage Davis–Beirut reaction as key steps.

Organic electrosynthesis is a rapidly evolving field, providing powerful methods to assemble targets of interest in organic synthesis. Concerns around the scalability of electrochemical methods remain the biggest reason behind their scarce implementation in manufacturing routes for the pharmaceutical industry. To fill this gap, we report a workflow describing the key reaction parameters toward the

This review describes the practical aspects involved in the implementation of large-scale amidations in process chemistry. Coupling reagent, base, additive, and solvent selections are critically analyzed to highlight their pros and cons. Other important factors to be considered on large scale, such as atom economy, cost, safety, and toxicity, are also examined. These concepts are then showcased through
