Abstract Oxazocines are key structural intermediates in the synthesis of natural products and pharmaceutical molecules. However, the synthesis of oxazocines especially in a highly enantioselective manner, is a long‐standing formidable challenge due

A strategy of C3/C4 and C5/C4 bis-C–H functionalization of furfural and 5-hydroxymethylfurfural is presented. This task has been accomplished by the initial iridium-catalyzed C–H borylation of furfural, equipped with an appropriate imine function

We reported palladium-catalyzed regioselective [3+2] cycloadditions of α,β-unsaturated imines with vinylethylene carbonates, providing the desired oxazolidines in moderate-to-high yields. This reaction provides a facile route for the highly regiose
