The stereochemical study of the cyclohexane ring part of enacyloxins (ENXs), a series of antibiotics isolated from Frateuria sp. W-315, was examined. The relative configuration was elucidated by the coupling constant values of the 1H NMR spectrum. The absolute structure was determined to be 1S, 3R, 4S, because the CD spectrum of the corresponding 3,4-dibenzoate derivative showed negative chirality. This conclusion was confirmed by the synthesis of the dibenzoate from tri-O-acetyl-D-glucal.
