(R)-tert-butyl-2-(aminomethyl)-2,3-dihydro-1H-pyrrolo[3,2-c]pyridine-1-carboxylate

Computational details:

600 confs. were generated using the universal force field (UFF), then filtered for duplicates using an RMS-threshold of 0.1 Å. The UFF conformers in a 10 kcal/mol (i.e. ~26) were relaxed using DFT level of theory, i.e., the ADF program, BP86 functional and the TZP basis set. IR and VCD spectra were calculated for the conformers in 5 kcal/mol, i.e. 26, conformers. Starting from the relative energies predicted with DFT, the Boltzmann factors have been optimised using a genetic algorithm (see DOI:10.1039/c9sc02866e for details).
