The determination of absolute configuration of chiral molecules is a long-standing problem in natural product chemistry. Herein we report the use of VCD spectroscopy and DFT calculations to assing the absolute configuration of six isomeric monoterpene chromane esters isolated from Peperomia obtusifolia (Piperaceae). This work reinforces the capability of VCD to determine unambiguosly the absolute configurationf of structurally complex molecules in solution, without the need of crystallization, ...
