An aerobic decarboxylative cross-coupling of α-aminoacids with diverse C–H nucleophiles has been realized using Cu2(OH)2CO3 (1 mol%) as the catalyst under air. This protocol enables highly efficient formation of various C(sp3)–C(sp3), C(sp3)–C(sp2) and C(sp3)–C(sp) bonds under simple conditions without the use of any ligand or extra oxidant, providing a practical approach to numerous nitrogen-containing

A highly efficient heterogeneous copper(I)-catalyzeddecarboxylative C–C coupling of α-amino acids with various carbon nucleophiles has been developed that proceeds smoothly in toluene at 110 °C by using an 2-aminoethylamino-modified SBA-15-supported copper(I) bromide complex as the catalyst and di-tert-butyl peroxide as the oxidant and provides a novel and practical approach for the synthesis of diverse

New reactions of azomethine ylides with nontraditional dipolarophiles are reported. Azomethine ylides, formed in situ via decarboxylative condensations of alpha-amino acids with aldehydes, undergo reactions with naphthols, indoles, alkynes, and nitroalkanes.

Azomethineylides are generated using either organocatalysts or metal catalysts via a ballet of decarboxylative C–N coupling choreographed by prolines. These strategies enable diastereoselective [3 + 2] cycloaddition, C–C coupling, and ring annulation, providing sustainable routes. The synthesized pyrrolizines and other heterocycles have potential applications in the development of crucial biomolecules
