Chiral alkylboron derivatives are versatile building blocks for asymmetric synthesis, they can be stereospecifically transformed into a range of functional groups, providing access to diverse molecules with high enantioselectivity . To further show the synthetic potential of this asymmetric decarboxylative reaction, a 1.5 mmol scale experiment was conducted, yielding 3a in comparable yield although using a lower equivalent ethyl gem-borazirconocene (2.5 equiv. versus 3.7 equiv.) (Figure ). The C(sp 3 )-B bond of the resulting chiral product was subsequently transformed to a new C(sp 2 )-C(sp 3 ) bond through stereospecific 1,2-boryl migration (Figure ). Additionally, it can be converted into a series of carbon-heteroatom bonds. The oxidation of 3a afforded secondary alcohol 5b. Amination with the H2N-DABCO reagent forged a new C-N 70 bond (5c). The stereospecific bromination of 3a produced alkyl bromide product 5d, which could readily undergo further functional group interconversions .
