The distinctive structural features and broad synthetic utility of carbohydrates have established them as key scaffolds in asymmetric synthesis.
This review summarizes the recently reported urea and thiourea-based small molecular chromofluorogenic chemosensors utilized for detecting diverse metal ions and anions.
We designed a series of bifunctional thiourea-based organocatalysts by combining two stereogenic elements, which promoted kinetic resolution polymerization of racemic lactide to produce isotactic polylactide with Pm up to 0.96.
Thiourea and squaramide organocatalysts have become essential tools in asymmetric synthesis, offering metal-free, highly selective methods for the efficient synthesis of complex natural products with important biological activities.
Organocatalysis has emerged as a powerful synthetic platform for classical asymmetric multicomponent reactions, demonstrating remarkable versatility in constructing diverse molecular architectures with precise stereochemical induction.
