We describe herein a novel stereoselective trans-iodoalkylation protocol by using three
components of nucleophilic dicarbonyl compounds, iodoform and terminal alkynes. The …

The 5-endo-trig radical closure has emerged as an ideal method for the fast aseembly of five-
membered rings. It is believed to be kinetically disfavored due to the stereoelectronic …

The synthesis of vinyl sulfones via silver-promoted cross-coupling of vinyl bromides with
sulfonyl hydrazides was realized. Water was used as the sole solvent. Multisubstituted vinyl …

Tandem anionic oxy‐Cope rearrangement/radical oxygenation reactions provide δ, ϵ‐
unsaturated α‐(aminoxy) carbonyl compounds, which serve as convenient precursors to …

Spirooxindoles, particularly 3, 3'-spirooxindoles constitute a privileged structural scaffold
owing to the intensive biological activities which they possess. Because of this over the last …

A promising and useful method has been accomplished for regio‐and diastereoselective
synthesis of tetrahydro‐benzofuro [3, 2‐c] chromenones through ceric (IV) ammonium nitrate …

Controlling of radical reactivity by binding a radical to the metal center is an elegant strategy
to overcome the challenge that radical intermediates are “too reactive to be selective”. Yet …

Radical reactions occupy a significant place in synthetic organic chemistry and significantly
complement and expand modern approaches to the synthesis of substituted coumarins. This …

endo-trig 自由基环化是快速构筑五元环的理想方法之一. Baldwin-Beckwith 规则指出,
受立体电子效应影响, 5-endo-trig 自由基环化通常是动力学不利的. 近年来 …

A catalytic conjugate addition-oxidation reaction of 1, 2-naphthoquinones has been
investigated. p-Toluenesulfnoic acid was found to be the most effective catalyst for the …
