Mild and efficient catalytic deprotection of ketals/acetals mediated by FeCl3·6H2O/acetaldehyde has been described in this paper. The versatility and high chemoselectivity of the iron(iii)/aldehyde system are demonstrated by a large scope of examples. Deprotected ketones/aldehydes are nearly quantitatively isolated after filtration over a pad of silica gel followed by evaporation of volatile by-products.
Improvements in the synthesis of adamantane-2,6-dione and preparation of the novel adamantane-2,6-dione mono-ketal
Ayres, Fred D.

A facile seven-step synthesis of adamantane-2,6-dione is presented that involves minimal purification, provides multigram quantities of product, and proceeds in an overall yield of 21%. The mono-ketal of adamantane-2,6-dione is obtained in 18% overall yield.
