M. , M. , and S. 1r, In contrast, 385 and 387 were was highly effective in the stereocontrol of helical chirality in Suzuki-Miyaura coupling (SMC) reactions as illustrated in entries 13-14 of Table 31, with the Suzuki coupling between diisopropyl (1-bromonaphthalen-2-yl) phosphonate 429 and o-tolylboronic acid 429' (up to 99% ee for product 430). The stereoselectivity of the reactions was elucidated with the help of DFT calculations, 99% yield with only 71% ee. Similarly, (M)-385 was also highly effective in the asymmetric allylation of indoles with 1,3-diphenylallyl acetate (up to 99% ee, entry 11), and in the etherification of alcohols (up to 96% ee, entry 12), 2003.
