asymmetric iodination of aldehydes using an axially chiral catalyst and 1,3-dicarbonyl compounds under mild conditions, synthesis of haloalkenes and haloalkynes by catalytic Hunsdiecker reaction, the reaction of alkynes and NIS/water to give α-diketones, highly enantioselective iodocyclization of polyp...
Herein we describe two coupling reactions of aldehydes and activated alkynes to give chalcones or alkenyl esters depending on the base used. Chalcones were... MFA Adamo,G Bellini,S Suresh - 《Cheminform》 被引量: 27发表: 2011年 Gluconic acid aqueous solution: a task-specific bio-based solvent...
Hydrogen sulfide (H2S) is an important endogenous gasotransmitter, but the bioorthogonal H2S donors are limited. Here, the authors design and synthesize sydnthiones, and investigate their bioorthogonal reactions with strained alkynes for mitochondria-targeted H2S release. ...

Spectroscopic and Theoretical Investigations of Electrophilic Bromination Reactions of Alkynes: The First Evidence for π Complexes as Reaction Intermediates The first direct detection of a 1:1 Br2–alkyne complex as an intermediate during the addition of Br2 to alkynes is reported. The measured negative...

Coupling reactions The carbon-carbon and carbon–heteroatom bond formation via coupling reactions is arguably one of the most important transformations in organic synthesis. Mizuno and his coworkers have reported an attractive and efficient approach for the synthesis of propargyl amines from the cross-de...
