, p. 9179 - 9187 (2008/02/10)
Diastereoselective synthesis of spiro-β-lactams via [2+2] cycloaddition reaction of imines and chiral ketenes is described. The chiral ketene was prepared from commercially available, inexpensive d-glucose. Although, theoretically four diastereomers are p
Synthesis of C1-C6 segment of carbonolide B: Wolff rearrangement of sugar α-diazo ketones

Silver benzoate catalysed Wolff rearrangement of a series of α-diazo ketones, derived from furanuronic acids, in methanol proceeds with good yields to produce the corresponding one carbon homologated methyl-5-deoxy- hexo-furanuronate. The utility of methy
Towards the synthesis of the squalestatins/zaragozic acids: Synthesis of an advanced intermediate and introduction of the C-1 sidechain
Mann, Robert K.,Parsons, Jack G.,Rizzacasa, Mark A.
, p. 1283 - 1293 (2007/10/03)
A highly convergent synthesis of a squalestatin/zaragozic acid A C-4-decarboxydeoxy intermediate has been achieved. The key step involves the construction of the C-1-C-1′ bond by the addition of a fully functionalized C-1 sidechain anion (derived from iod
Short Synthetic Route to Congeners of the Undecose Antibiotic Herbicidin
Bearder, John R.,Dewis, Mark L.,Whiting, Donald A.
, p. 227 - 234 (2007/10/02)
The undecose backbone of the herbicidins has been assemled via direct alkylation, hydroxyalkylation, or acylation of the cyclic vinylanion 5 with the xylofuranose triflate 14, aldehyde 6, or acid chloride 10, respectively.
