Synthesis of the syributins and formal total synthesis of syringolide 1
Di Florio, Romina,Rizzacasa, Mark A.
, p. 327 - 331 (2000)
A synthesis of syributins 1 (5) and 2 (6) from D-glyceraldehyde acetonide (12) and furans (14) and (15) is described. Compounds (5) and (6) are cometabolites of the novel non-proteinaceous C-glycosidic elicitor molecules the syringolides 1 (1) and 2 (2). Under a variety of acidic conditions, the intermediate butenolides (9) and (10) provided syributins 1 (5) and 2 (6). Similar results have been reported by Honda and coworkers who converted butenolide (20) into syringolide 1 (1). Since compound (20) was also synthesized by the present new route, a formal synthesis of syringolide 1 (1) has been achieved. CSIRO 2000.
Synthesis of Penta-2,4-dien-1-imines and 1,2-Dihydropyridines by Rhodium-Catalyzed Reaction of N-Sulfonyl-1,2,3-triazoles with 2-(Siloxy)furans

supporting information, p. 6284 - 6287 (2016/12/23)
A rhodium(II)-catalyzed reaction of N-sulfonyl-1,2,3-triazoles with 2-(siloxy)furans is reported. Either open-chain penta-2,4-dien-1-imines or cyclic 1,2-dihydropyridines are selectively obtained depending on the ligand on rhodium(II).
Synthetic studies on azadirachtin: Asymmetric synthesis of the tetracyclic decalin part of azadirachtin
Kanoh,Ishihara,Yamamoto,Murai
, p. 1878 - 1893 (2007/10/03)
A synthesis of the tetracyclic decalin part of azadirachtin in the naturally occurring form is described. The key reactions involve the Corey-Bakshi-Shibata (CBS) asymmetric reduction of the ketone, and an intramolecular Diels-Alder (IMDA) reaction.
2-Siloxy-4-furanyl anion: Remarkable solvent effect on its nucleophilicity
Xin,Zheng,Stewart
, p. 1324 - 1326 (2007/10/03)
A significant solvent effect was observed for 2-triisopropylsiloxyl-4-furanyllithium complex (II) in nucleophilic addition of ketones. THF was found to be the best solvent in terms of yields and diastereoselectivity.
