Base-Controlled Diastereoselective Synthesis of Either anti- or syn-β-Aminonitriles
摘要:
Deprotonation of secondazty alkane nitriles with nBuLi and addition to aryl imines gives kinetic anti-beta-aminonitriles. Use of LHMDS allows reversible protonation of the reaction intermediate to give syn-beta-aminoriitriles. The pure diastereosiomers can be isolated in good yields, and the mechanism was elucidated.
