Chemoselective reactions of a compound containing both aldehyde and ozonide groups
摘要:
The aldehyde of compound 2 is more reactive than the ozonide in the carbon-carbon bond formation reactions. The ozonide is stable under the Lewis acid, radical and organometallic conditions where aldehyde reacts efficiently. The ozonide moiety can be considered as a synthon or protecting group for the aldehyde and carboxylic acid.

Molecules containing a hydroxy or aldehydegroup tethered with a tri-substituted ozonide moiety were prepared. We have demonstrated that the ozonidegroup is stable under certain Lewis acidic, free radical, and organometallic conditions. Therefore, chemoselective elaboration of the hydroxy or aldehydegroup is possible under these conditions. These functional group transformations followed by the decomposition
