The first total synthesis of the potent glycosidase inhibitors 1-O-β-D-glucopyranosyl-5-deoxyadenophorine and its aglycon congener is described in respectively 13 steps (9% overall yield) and 9 steps (29% overall yield) from (R)-Garner aldehyde. The synthesis takes advantage of several key reactions including a diastereoselective allylation of a chiral imine, a stereoselective epoxidation, and a glycoside coupling. In addition this study established unambiguously the absolute configuration of the natural products.
Efficient access to chiral trans-2,6-dialkyl-1,2,5,6-tetrahydropyridines via allylation of chiral imines and ring-closing metathesis

, p. 527 - 530 (2007/10/03)
Enantiomerically pure trans-2,6-dialkyl-1,2,5,6-tetrahydropyridines are synthesized in five steps from Garner's aldehyde in 37-44% overall yield. This strategy is based on the allylation of chiral iminoalcohols formed in situ followed by a ring-closing metathesis.
Synthesis of asymmetric (E)-α-(2-phenylcyclopropyl)glycines

, p. 541 - 542 (2007/10/02)
An asymmetric synthesis of (E)-α-(2-phenylcyclopropyl)glycines is reported. The key step is the dibromocyclopropanation of tert-Butyl (E,4R) or (E,4S)-2,2-dimethyl-4-(2'-phenylvinyl)-3-oxazolidinecarboxylates, easily prepared from L or D-serine, respectiv
