Abstract Oxazocines are key structural intermediates in the synthesis of natural products and pharmaceutical molecules. However, oxazocines especially a highly enantioselective manner, is long‐standing formidable challenge due to unfavorable energetics involved cyclization. Herein, series new PNP‐Ligand P ‐chiral stereocenter first designed synthesized, called MQ‐Phos , successfully applied it Pd‐catalyzed higher‐order formal [4+4]‐cycloaddition α β ‐unsaturated imines with 2‐(hydroxymethyl)‐1‐arylallyl carbonates. The reaction features mild conditions, excellent regio‐ enantiocontrol broad substrate scope (54 examples). Various medium‐sized rings can be afforded moderate yields (up 92%) enantioselectivity 99% ee). newly developed critical for ring catalytic reactivity enantioselectivity.

A novel method was devised for regioselective ring expansion of spirocyclopropanes to spirocyclobutanes with stabilized sulfonium ylides, affording 1,2- trans -disubstituted 6,8-dioxaspiro[3.5]nonane-5,9-diones without the formation any isomers.

Abstract Silaspiranes bearing a spiro‐silicon center are promising ring frameworks for the synthesis of novel spirocyclic molecules possessing unique properties. Development efficient methods towards these structures has therefore attracted considerable attentions synthetic chemists. This minireview highlights representative advances in field, and is categorized into four parts according to formation strategies: cyclization, annulation, expansion cycloaddition.

Abstract Under the catalysis of Rh 2 (OAc) 4 (10 mol%) and (±)‐Me‐Pybox (20 in 1,2‐DCE at 80 °C, homocoupling/[4+1] cycloaddition cascade diazobarbiturates with diazopyrazolones proceeded readily provided spirobarbiturates 32–88% chemical yields. The structure obtained was identified by X‐ray diffraction analysis.
