The photooxygenation of E- as well as Z-configurated γ-hydroxyvinylstannanes proceeded in high regio- and diastereoselectivity to yield, after subsequent triphenylphosphine reduction, the corresponding threo-stannyl diols 2 in high excess. Their acylated derivatives showed only low and solvent-dependent stereoselectivity, which was not significantly influenced by the steric and electronic demand of
