3-Methyl-2-propionamido-butanoic acid

Area of Science:

• Organic Chemistry
• Crystallography

Background:

• Chemical synthesis often yields unexpected products.
• Understanding reaction pathways is crucial for novel compound discovery.

Purpose of the Study:

• To characterize the unexpected product formed from the reaction of propionyl isothiocyanate and valine.
• To elucidate the molecular structure and intermolecular interactions of the synthesized compound.

Main Methods:

• Reaction of propionyl isothiocyanate with valine.
• Single-crystal X-ray diffraction to determine molecular and crystal structure.
• Analysis of hydrogen bonding networks.

Main Results:

• The reaction produced C(8)H(15)NO(3) instead of the anticipated thio-urea.
• The molecule exhibits a non-planar conformation with a cis configuration of the carbonyl and methyl-butanoic acid groups.
• Intermolecular hydrogen bonds (O-H⋯O and N-H⋯O) form a 2D network parallel to the (100) plane.

Conclusions:

• The study details the unexpected formation and structural characterization of a novel organic compound.
• The findings highlight the importance of structural analysis in organic synthesis to identify unforeseen products.
• The identified 2D hydrogen-bonded network provides insights into crystal engineering and supramolecular chemistry.
