Summary
Cleavage of dithioacetal using perchloric acid in acetonitrile yields aldehyde, cyclic acylal, and acetal. Acetone solvent forms acetonide, confirmed by X-ray crystallography.
Area of Science:
- Organic Chemistry
- Synthetic Chemistry
Context:
- Dithioacetals are versatile synthetic intermediates.
- Acid-catalyzed cleavage is a common synthetic transformation.
Purpose:
- To investigate the cleavage of dithioacetal 3B under different reaction conditions.
- To characterize the resulting products, including a novel acetonide.
Summary:
- Cleavage of dithioacetal 3B with perchloric acid in acetonitrile afforded the aldehyde 5, cyclic acylal 6, and acetal 8.
- Using acetone as the solvent resulted in the formation of acetonide 7.
- The structure of acetonide 7 was unequivocally confirmed through X-ray structure determination.
Impact:
- This study expands the synthetic utility of dithioacetals.
- Provides a new route to functionalized aldehydes, acylals, and acetals.
- Highlights the role of solvent in directing the outcome of acid-catalyzed cleavage reactions.
