摘要:
Uncatalyzed one-pot, three-component reactions of aldehydes, chiral alpha-methylamines, and dimethyl phosphite under solvent-free conditions were used for the diastereoselective synthesis of alpha-amino phosphonates. The reactions proceeded with extremely high efficiency under mild conditions and gave good yields and diastereoselectivities (70:30 to 93:7 dr). This approach could be useful for the large-scale synthesis of several alpha-amino phosphonates.
