Trimethyltin hydroxide Usage And Synthesis

Chemical Properties

Trimethyltin hydroxide is a colorless, white crystals. It is soluble in water and many organic solvents. It is commercially available in the form of large, needle-shaped, crystals with a significant propensity for twinning along the needle axis. The twinning of the trimethyltin hydroxide needle shaped crystals makes finding a single crystal for data collection very difficult.

Uses

Trimethyltin hydroxide is used in the synthesis of modified thymines, which is useful as inhibitors of RNase A. It is also used in the preparation of ketoheterocycle inhibitors of fatty acid amide inhibitors. It reacts with 2,2-disubstituted benzothiazolines to form trialkyltin derivatives of sulphur containing Schiff base complexes.

Reactions

The synthesis of N-Boc-N-(2-(tritylthio)ethoxy)glycine (4) is illustrated in Scheme 2. O-(2-(tritylthio)ethyl)hydroxylamine (1) was synthesized using the literature method. The aminooxy group was then protected with Boc, followed by alkylation with methyl bromoacetate in the presence of sodium hydride. Saponification of the methyl ester with trimethyltin hydroxide afforded N-Boc-N-(2-(tritylthio)ethoxy)glycine (4) in an overall yield of 19% after three steps of reactions. The Boc and Trt protecting groups in building block 4 are stable to Fmoc SPPS and are readily removable by treatment with trifluoroacetic acid (TFA).

Hazard

A poison.
