An Efficient Access to (Z)-Vinyltin Acetals via Titanation of the Corresponding Alkynyltins
Launay, Valérie,Beaudet, Isabelle,Quintard, Jean-Paul
, p. 821 - 823 (1997)
Titanation of alkynyltin acetals has been exploited to obtain the corresponding (Z)-disubstituted vinyltins and γ-hydroxy trisubstituted vinyltins, as a single geometrical isomer.
Reactions with Phosphine Alkylenes, 44. A Further Synthesis of (Z)-α,β-Unsaturated Aldehydes
Bestmann, Hans Juergen,Ermann, Peter
, p. 3264 - 3266 (2007/10/02)
Reaction of phosphorus ylides 4, especially such with electron donating groups R, with the glyoxal semiacetal 5 leads Z-stereospecifically to the formation of the acetals 3, which can be cleaved to the (Z)-α,β-unsaturated aldehydes 6.
