Diastereo- and enantioselective synthesis of protected vicinal silylamines via 1,2-addition to α-silyl-hydrazones
摘要:
Nucleophilic 1,2-addition of MeLi/CeCl3 to alpha-silylaldehyde-SAMP-hydrazones 2 and subsequent reductive NN bond cleavage affords protected vicinal silylamines 4 in good yields with high diastereomeric and enantiomeric excesses. (C) 1997 Elsevier Science Ltd.
