Abstract An exclusively regioselective hydrocyanation of monofluoroalkenes has been developed, with which a series aliphatic quaternary α-fluoronitriles were synthesized in facile and efficient manner. This novel method is featured mild conditions, good functional groups compatibilities, high reactivity.

A mild electrochemical method for the regioselective preparation of 1-tetralones under environmentally friendly conditions from readily available cyclobutanols was developed. series aromatic- and heteroaromatic-fused accessed through ring expansion functionalized via generation alkoxy radicals intramolecular cyclization.

The reactivity of a series pairs bent and linear three-atom-component (B-TACs L-TACs) participating in [3 + 2] cycloaddition (32CA) reactions towards ethylene electrophilic dicyanoethylene (DCE) have been studied within the Molecular Electron Density Theory. While pseudodiradical structure B-TACs changes to that pseudoradical or carbenoid L-TACs upon dehydrogenation, zwitterionic remain unchang...

regioselective diels-alder reactions of acyl-1,4-benzoquinones 1 with, severally, isoprene, trans-piperylene,1-acetoxy-1,3-butadiene and 1-methoxy-1,3-butadiene gave the corresponding adducts 2 in high yield. treatment of the adducts 2 with manganese dioxide gave regiospecifically the corresponding 1,4-naphthoquinones 3. in several cases, the adducts of the acetylquinones afforded intermediates...

Abstract Regioselective tritylation and carbonate aminolysis were employed in this work to synthesize cellulose 2,3- bis (3,5-dimethylphenyl carbamate)-6-( α -phenylethyl carbamate)-type chiral selectors. We evaluated optimized the critical aspects of regioselective detritylation at C6 glucopyranose units polysaccharide backbone. The advantage using II comparison I for was analyzed time determi...
