Stereoselective synthesis of (E) or (Z) α-alkenylphosphonates via α-stannylated phosphonates
Mimouni,About-Jaudet,Collignon,Savignac
, p. 2341 - 2348 (2007/10/02)
α-lithiostannylalkylphosphonates react with aldehydes with the complete elimination of the organotin moiety. The stereoselective formation of the (E) or (Z) α-alkenylphosphonates is closely dependent on the tin substituent.
