<p>Solid-supported optically active binaphthyls, a process for preparing the binaphthyls or intermediates thereof, and an efficient process for preparing asymmetric amino nitriles by using the same. The solid-supported optionally active binaphthyls are represented by the general formula (1) or (1'), and asymmetric amino nitriles can be prepared from imines and trimethyl cyanide by using the same: (1') wherein R1 is phenyl or the like; R2 is hydrogen or the like; R3 is hydrogen or the like; A- represents a polymer; and B- represents optionally substituted alkylene or the like.</p> |
