COMPOUND OVERVIEW
tert-butyl(((3aS,4R,6aR)-2,2-dimethyltetrahydrothieno[3,4-d][1,3]dioxol-4-yl)methoxy)diphenylsilane | CAS 03-08-5336Â is a stereochemically defined silyl ether with a fused thieno[3,4-d][1,3]dioxole core. The compound combines:
-
A thieno ring (a sulfur-containing heterocycle) contributing ring rigidity and unique electronic character.
-
A dioxolane moiety that is often used as a protecting group or chiral auxiliary in carbohydrate synthesis.
-
A diphenylsilyl group (tert-butyldiphenylsilyl, TBDPS) known for its robust hydroxyl protection in multi-step synthesis.
This design makes it valuable in situations where protecting group stability and stereochemical integrity are critical.
KEY FEATURES & BENEFITS
-
High Stereochemical Purity: The specified (3aS,4R,6aR) configuration ensures consistent outcomes in asymmetric synthesis applications.
-
Robust Protecting Group: The tert-butyldiphenylsilyl (TBDPS) group confers high resistance to acidic and basic conditions compared to smaller silyl protecting groups (e.g., TMS or TES), making this material ideal for prolonged synthetic routes.
-
Versatile Intermediate: Useful for the protection of primary and secondary hydroxyls when designing complex molecules, including carbohydrate analogs, heterocycles, or natural product derivatives.
-
Functional Group Compatibility: The fused heterocycle can provide sites for further modification through well-established organic transformations (oxidation, substitution, cross-coupling).

Organic Synthesis & Method Development
This compound is commonly employed as a protected intermediate in the preparation of more complex molecules. The diphenylsilyl protecting group is widely used due to its:
-
Stability to a variety of reaction conditions: including strong bases and mild acids.
-
Selective deprotection: The TBDPS group can be removed selectively in the presence of other protecting groups using fluoride ions (e.g., TBAF), facilitating orthogonal protection strategies.
Carbohydrate Chemistry
The dioxolane ring system makes this compound relevant in carbohydrate synthesis where:
-
Protecting group strategies are essential for controlling reactivity.
-
The thieno ring may act as a bioisostere for oxygen in medicinal chemistry efforts.
Pharmaceutical & Medicinal Chemistry
Though not a final API, this intermediate can be used to build heterocyclic scaffolds or glycomimetic structures — both of which are valuable in drug discovery programs targeting enzymes, receptors, or transporters.
Academic Research
