De Souza,Da Silva,Ferreira
, p. 1339 - 1340 (1998)
1,2;3,4-Di-O-isopropylidene-D-erythronic acid (2,2,2′,2′-Tetramethyl-[R,R-(4,4′-bi-1,3-dioxolan)]-5-one) 4, a new C4 chiral building block derivative of D-erythronic acid was prepared in two steps from D-glucono-δ-lactone.

Liu, Xiaojing,Chen, Ruijiao,Duan, Feixia,Jia, Junhao,Zhou, Yuqin,Chen, Xiaochuan
, p. 3947 - 3950 (2017)
The first synthesis of (+)-botryolide-E and its C-7 epimer has been achieved in 8 steps from D-Glucono-δ-lactone, and their antibiotic activities were also investigated preliminarily.
Total Synthesis of Anti-Influenza Agents Zanamivir and Zanaphosphor via Asymmetric Aza-Henry Reaction
Lin, Long-Zhi,Fang, Jim-Min
, p. 4400 - 4403 (2016)
The potent anti-influenza agents, zanamivir and its phosphonate congener, are synthesized by using a nitro group as the latent amino group at C4 for asymmetric aza-Henry reaction with a chiral sulfinylimine, which is derived from inexpensive d-glucono-?-lactone to establish the essential nitrogen-containing substituent at C5. This method provides an efficient way to construct the densely substituted dihydropyran core of zanamivir and zanaphosphor without using the hazardous azide reagent.
Stereoselective Synthesis of the C1-C9 and C11-C25 Fragments of Amphidinolides C, C2, C3, and F
Akwaboah, Daniel C.,Wu, Dimao,Forsyth, Craig J.
supporting information, p. 1180 - 1183 (2017/03/14)
An efficient synthesis of the C1-C9 and the C11-C25 fragments of amphidinolides C, C2, C3, and F from a common intermediate is reported. The construction of the C1-C9 fragment involves an intramolecular hetero-Michael cyclization to form the 3,5-disubstituted trans-tetrahydrofuran moiety. The approach to prepare the C11-C25 fragment utilizes a highly stereoselective aerobic cobalt-catalyzed alkenol cyclization and a chelated Mukaiyama aldol reaction to form the C13-C14 bond and to concomitantly install the C13 hydroxyl group.
