    • The yield of the phenylation product 3aa was lower (47%) with a smaller amount (0.06 mmol (0.18 mmol of B)) of (PhBO)3. The reaction of 6a with PhB(OH)2 and PhBF3K in place of (PhBO)3 under the same conditions for entry 10 in Table 1 gave 3aa, in 78% yield (95% ee) and in <3% yield, respectively

    • In the absence of rhodium catalyst, the reactions in entries 5 and 6 under otherwise same conditions gave the arylation products in 58% (3be) and 5% (3bb) yields, respectively. The rhodium-catalyzed reaction at 23 °C gave 3be with 72% ee albeit in a low yield (40%).
