herein report the first example of iridium‐catalyzedenantioselectiveC(sp3)–Hborylation of cyclobutanes using benzoxazoline as the directing group. The combination of a chiral bidentate boryl ligand and an iridium precursor has found to effectively catalyzeC(sp3)–Hborylation to afford a variety of cyclobutylboronates with good to excellent enantioselectivities. We also demonstrate the synthetic
Phase transfer alkylations of phenylacetonitrile derivatives carried out in the presence of 60–75% aqueous KOH, instead of the typical 50% NaOH, provide substantial improvements in the overall yields and purity of products. Reactions with simple secondaryalkylhalides, as well as cycloalkylations with 1,2- and 1,3-dihaloalkanes proceed with good yields. Increasing the concentration of base diminishes
