The preparation of the intermediate aminoboronate (VII) is shown in Scheme 27968701a. Addition of catecholborane (II) to allyl bromide (I) provided boronic ester (III). Subsequent exchange with (+)-alpha-pinanediol (IV) afforded the chiral borane (V). Insertion of dichloromethyllithium in (V) produced the alpha-chloroboronic ester (VI). The required amino compound was then obtained by displacement of the halogen with lithium hexamethyldisilazide, followed by acid-catalyzed desilylation.
