摘要:
NMR studies on delta-decanolide samples obtained from 1 and 5 in reduction experiments with baker's yeast in D2O and H2O, respectively, show that the double bond saturation involves beta re-face trans formal addition of hydrogen atoms, arising to a large extent from water. The reduction does not depend on the absolute configuration at position 5 and shows a kinetic preference for the (R) enantiomer.
