- γ-Keto esters and lactones were fully characterized by spec-troscopic means and were prepared by independent methods. Spiro lactone 7 was identical to a sample prepared by photooxidation of 2-furylbutanol-27. We do not have a satisfactory explanation for the reaction of 6 with TMSI.

- The selectivity of the reaction with dimethoxydihydrofurans is remarkable as the dimethoxyacetals of α,β-unsatur ated aldehydes such as acrolein and β-phenylacrolein yielded complex product mixtures in their reactions with TMSI
- Deketallzation is the major reaction of 2,5-disubstituted 2,5-dimethoxydihydrofurans e. g. 2,5-dimethyl-2,5-dimethoxydihydrofuran gives 3-penten-2,5-dione in 82 % yield
