The first asymmetrictotalsynthesis of the unnatural enantiomer of cytotoxic awajanomycin (1) is reported. The synthetic approach features first a convergent strategy using the cross-olefin metathesis reaction to link the lipid side chain 2 and the piperidinone core structure 3. The second feature of the synthesis resides on the construction of segment 3 from the building block 5 via a three-component
N-Allyl protected 3-O-benzyloxglutarimide 11 was synthesized as a useful variant of the chiral building block 10. This modification allowed a high-yielding deprotection of the allyl group from the lactam intermediate 14. Starting from this building block, the asymmetric syntheses of aza-sugars 6-deoxyfagomine (2), D-rhamnono-1,5-lactam (6), as well as D-deoxyrhamnojirimycin (5) have been achieved in high regio- and/or diastereo-controlled manner.
