Mixed acetals of olefinic and acetylenic alcohols and β-carbonyl and other substituted aldehydes are readily obtained by acetoxy-mercuration followed by demercuration utilizing NaBH4 or Na2CS3.

the feasibility of the use of an acetal as the linking group for the diene and dienophile in the intramolecularDiels-Alderreaction has been demonstrated. Although some limitations were encountered, in general the mixed acetals examined showed excellent thermal stability with no tendency to undergo elimination of methanol even at temperatures in excess of 200°C for several hours providing the expected
