short, protecting group-free totalsynthesis of bruceollines D, E, and J has been achieved. The enantioselective reduction of bruceolline E with β-chlorodiisopinocampheylborane delivers both the natural and unnaturalenantiomers of bruceolline J in excellent yields and enantioselectivities. Reduction with baker’s yeast and sucrose was shown to provide the unnaturalenantiomer of bruceolline J in 98% ee
