Man, Hon-Wah published the artcileA Highly Enantioselective and Diastereoselective Synthesis of Cyclobutanes via Boronic Esters, COA of Formula: C10H18BNO2, the publication is Organic Letters (1999), 1(3), 379-381, database is CAplus and MEDLINE.
Deprotonation of enantiopure (R,R)-1,2-dicyclohexyl-1,2-ethanediol 1-chloro-4-cyanobutylboronates with LDA followed by treatment with anhydrous magnesium bromide yields (R)-(trans-2-cyanocyclobutyl)boronic esters 7 in high diastereomeric and enantiomeric purity. No cyclobutane formation has been observed in the absence of at least a catalytic amount of magnesium halide.
Organic Letters published new progress about 238088-16-9. 238088-16-9 belongs to nitriles-buliding-blocks, auxiliary class Nitrile,Boronic acid and ester,Aliphatic cyclic hydrocarbon,Boronic Acids,Boronate Esters, name is 4-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)butanenitrile, and the molecular formula is C10H18BNO2, COA of Formula: C10H18BNO2.
