, p. 4613 - 4616 (1983)
Cycloadditions of ketene acetals (R1R2C=C(OR)2) with carbonyl compounds (R3COR4) are strongly promoted by increase of pressure.At 12 kbar oxetanes are even obtained from very polar ketene acetals (R1,
Chemistry of Ketene Acetals. Part 8. Stereochemistry of the Reaction of 1,1-Dimethoxypropene with Aldehydes
Hofstraat, Rob G.,Scheeren, Hans W.,Nivard, Rutger J. F.
, p. 561 - 564 (2007/10/02)
The Lewis acid-catalysed (2+2)cycloadditions of 1,1-dimethoxypropene with various aldehydes RCHO have been studied.These reactions, which are supposed to proceed via dipolar intermediates, yield 2,2-dimethoxyoxetanes, the formation of which is reversible
