Ma, Winson M. J. published the artcileSynthesis of Amines with Pendant Boronic Esters by Borrowing Hydrogen Catalysis, Application of 1-(3-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)benzyl)piperidine, the publication is Organic Letters (2013), 15(18), 4850-4853, database is CAplus and MEDLINE.
Amine alkylation reactions of alcs. were performed in the presence of boronic ester groups to provide products which are known for their use as mol. sensors. E.g., reaction of (4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)methanol with morpholine in the presence of 2.5 mol% [Ru(p-cymene)Cl2]2 and 5 mol% DPEphos ligand in xylene/Na2CO3 at 155° to give (4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzyl)morpholine in 84% yield. The boronic ester moiety could be present in either the alc. or amine starting material and was not compromised in the presence of a Ru catalyst.
