The chemical space of chiral Brønsted acid catalysts is defined by quantity and complexity, reflecting the diverse synthetic challenges confronted innovative molecular designs introduced. Here, we detail how this successful outcome a powerful demonstration benefits utilizing both local structure searches comprehensive understanding catalyst performance for effective efficient exploration properties. In concept article provide an evolutionary overview field summarizing approaches to optimization, resulting structures, functions.

The development of recyclable catalysts has gained more attention in recent years order to minimize the environmental effect and overall cost catalytic processes. Some most broadly used chiral organocatalysts are BINOL-derived phosphoric acids, making it necessary develop efficient recycling strategies. While literature reports require up 13 synthetic steps access here we report a general concise 9-step approach anthracene decorated heterogeneous acids (PS-Anth), which have shown high performance either batch or continuous flow without observing catalyst degradation.
