Abstract
Chemical investigation of the alkaloid extract of the aerial parts of Schizanthus tricolor led to the targeted isolation of 26 hygroline derivatives of which 20 were fully characterized. They have not yet been described in the literature and their structures were established by 1D and 2D NMR, UV and IR spectroscopy, and HRESIMS. The configuration was determined by Gauge-Independent Atomic Orbital NMR chemical shift calculations supported by the advanced statistical method DP4 plus, vibrational circular dichroism, and measurement of optical rotation. Their anti-trypanosomatid, antiplasmodial and cytotoxic activities were measured. Several compounds exhibited low micromolar activity against Plasmodium falciparum. None of the identified molecules was cytotoxic.

Abstract
We report the application of VCD spectroscopy for the characterization of clarithromycin and erythromycin. We show that the VCD spectra of these large macrolides are distinctly different and that spectra calculations reproduce the experimentally observed VCD signatures. In addition, computed VCD spectra of different epimers indicate that they should also be distinguishable from the correct structure of clarithromycin.

Abstract
A reliable and convenient method for determining the configuration and conformation of the furanose ring in carbohydrates and nucleosides by vibrational circular dichroism (VCD) spectroscopy is described. Diastereomeric pairs of several furanose monosaccharides and nucleosides were prepared, and their VCD spectra were analyzed. The results revealed that VCD spectroscopy elucidates the equibrated state of the furanose ring puckers, which is often difficult to study by other techniques.

Abstract
The stereochemistry of glycerophospholipids (GPLs) has been of interest for its roles in the evolution of life and in their biological activity. However, because of their structural complexity, no convenient method to determine their configuration has been reported. In this work, through the first systematic application of vibrational circular dichroism (VCD) spectroscopy to various diacylated GPLs, we have revealed that their chirality can be assigned by the sign of a VCD exciton couplet generated by the interaction of two carbonyl groups. This paper also presents spectroscopic evidence for the stereochemistry of GPLs isolated from bacteria, eukaryotes, and mitochondria.

Abstract
The electronic circular dichroism (ECD), optical rotation dispersion (ORD), and vibrational circular dichroism (VCD) spectra of a pair of enantiomers, i.e. 3 and 4, of a bicyclo[3.1.0]hexane derivative have been measured in acetonitrile and acetonitrile-d(3), respectively. Extensive conformational searches at the B3LYP/6-311++G** level have been carried out for 3, which has four OH and one N(3) functional groups. For the bicyclo[3.1.0]hexane ring of 3, the boat-like conformers have been found to be much more stable than the chair-like conformers, while the number and the strength of the intramolecular hydrogen bonds have been identified as the dominant factors in the relative stability among the boat-like and among the chair-like conformers. DFT simulations of the ECD, ORD and VCD spectra have been performed for all low energy conformers at the B3LYP/6-311++G** and B3LYP/aug-cc-pVDZ level. Implicit continuum polarization model has been used to account for solvent effects in all these chiroptical measurements. Comparison of the DFT simulations with the experimental data shows that all three chiroptical properties yield the same absolute configuration assignment for . This work demonstrates that using multiple chiroptical spectroscopic methods in combination with DFT calculations allows one to determine absolute configurations with high confidence for chiral carbohydrates and their analogues, which possess a large number of rotatable bonds.

Abstract
Systematic VCD studies of N-acetylneuraminic acid (Neu5Ac), a recognition-related unique carbohydrate, were performed for the first time. Two pairs of anomeric isomers regarding a quaternary C2 asymmetric carbon of Neu5Ac derivatives were synthesized. VCD spectral patterns around the ester carbonyl region, as well as other Mid-IR regions, would be practical markers to distinguish the C2 stereochemistry.
