(S)-tert-Butyl (1-cyanopropan-2-yl)carbamate(CAS: 172695-22-6)

(S)-tert-Butyl (1-cyanopropan-2-yl)carbamate is a white crystalline solid with a molecular weight of approximately 174.25 g/mol. It is slightly soluble in water but highly soluble in organic solvents. This compound is known for its reactivity in amide bond formation and its ability to act as a carbamate precursor. It decomposes above 150°C and is sensitive to strong bases and acids.

(S)-tert-Butyl (1-cyanopropan-2-yl)carbamate is typically synthesized through the reaction of tert-butyl cyanopropyl carbonate with tert-butylamine. The synthesis involves the formation of a carbamate intermediate, which is then converted to the desired (S) enantiomer via kinetic resolution using chiral auxiliaries or enzymatic methods, ensuring high selectivity and yield.

(S)-tert-Butyl (1-cyanopropan-2-yl)carbamate finds applications in the pharmaceutical industry, particularly in the synthesis of chiral molecules for drug development. It is also used in the production of polymers and in the development of sensors and semiconductors due to its reactivity and specific enantioselectivity.

When handling (S)-tert-Butyl (1-cyanopropan-2-yl)carbamate, it is essential to wear appropriate personal protective equipment (PPE), such as gloves, goggles, and a lab coat. Work should be conducted in a fume hood to minimize exposure. Spills should be cleaned up immediately using appropriate absorbent materials. Always refer to the Material Safety Data Sheet (MSDS) for detailed safety information and emergency procedures.
