## Abstract A preparatively useful one‐step transformation of __γ__,__γ__‐disubstituted __α__‐formyl‐__γ__‐lactones into trisubstituted __γ__,__δ__‐unsaturated aldehydes is described, by means of catalytic amounts of either AcOH or AcOEt in the vapor phase over a glass support.

o-Trimethylsilyloxy-a-diazo-b-ketophosphonates were prepared in two steps from g-lactones. After exposure to catalytic rhodium(II) in refluxing toluene and further aqueous treatment, they gave rise to a-phosphono-d-lactones in moderate to good yields.
