General description

3-Hydroxy-3-methylbutyronitrile is a β-hydroxynitrile. It undergoes thermal degradation in gas phase via a six-membered cyclic transition state. 3-Hydroxy-3-methylbutyronitrile can be synthesized from 2-hydroxy-2-methyl-1-bromopropane.

Application

3-Hydroxy-3-methylbutyronitrile may be used to synthesize 1,1-dimethylcyanoethyl bromoacetate.

Phosphonoacetate and thiophosphonoacetate oligodeoxynucleotides were prepared via a solid-phase synthesis strategy. Under Reformatsky reaction conditions, novel esterified acetic acid phosphinodiamidites were synthesized and condensed with appropriately protected 5'-O-(4, 4'-dimethoxytrityl)-2'-deoxynucleosides to yield 3'-O-phosphinoamidite reactive monomers. These synthons when activated with tetrazole
