Data on nitrogen-containing derivatives of fumaropimaric acid

Area of Science:

• Organic Chemistry
• Catalysis
• Spectroscopy

Background:

• Levopimaric acid, a diterpene, serves as a precursor for novel chiral diamines.
• Asymmetric catalysis is crucial for synthesizing enantiomerically pure compounds.
• The Henry reaction is a fundamental carbon-carbon bond-forming reaction.

Purpose of the Study:

• To provide comprehensive spectroscopic data (1H, 13C NMR, IR) for levopimaric acid-derived 1,2-diamines.
• To present GC-MS data of pine oleoresin as the starting material.
• To support the findings of the related research paper on asymmetric Henry reactions.

Main Methods:

• Nuclear Magnetic Resonance (NMR) spectroscopy (1H and 13C) for structural elucidation.
• Infrared (IR) spectroscopy for functional group identification.
• Gas Chromatography-Mass Spectrometry (GC-MS) for analysis of the starting material.

Main Results:

• Detailed NMR and IR spectra are provided for the synthesized diterpene derivatives.
• GC-MS analysis confirms the composition of the pine oleoresin precursor.
• The data facilitates the understanding of the structure-activity relationship in asymmetric catalysis.

Conclusions:

• The presented data validates the synthesis and characterization of novel chiral diamines.
• This dataset is valuable for researchers in asymmetric synthesis and catalysis.
• The findings contribute to the development of efficient catalytic systems for chiral molecule production.
