    • note
    • Using a phosphinediamine ligand in which a p-methyl substituent was introduced into the phenyl units of the ligand 1b, the reaction was faster and the selectivity was higher than with 1b. For 2-methylcinnamic acid under the conditions of 60 atm and 25°C, the enantioselectivity was 90% ee while 1b gave 81% ee.
