Chemically labile stannylene-nitrogen bonds. The chemoselective and stereoselective synthesis of N,N-bis(trimethylsilyl)enamines and N,N-dialkylenamines
摘要:
The chemoselective reaction of Sn[N(TMS)2]2 with primary aldehydes leads to the stereoselective synthesis of trans-N,N-bis(trimethylsilyl)enamines. More reactive Sn(NR2)2 (R = Et, iPr, or piperidine) can be generated in situ and then treated with aldehydes or ketones to give trans enamines.
A new synthesis of N,N-bis(trimethylsilyl)enamines from straight chain olefinic amines has been devised which makes use of iron pentacarbonyl photocatalysed isomerisation. Complete conversion of the olefinic amines to the enamines was observed for substituted N,N-bis(trimethylsilyl)allylamines and non-allylic amines. The enamines obtained are potential sources of aldehydes and precursors of substituted
