Preliminary studies into the use of ring-closing metathesis (RCM) in a convergent approach for the total synthesis of bryostatins are described. An ester that would have provided an advanced intermediate for a synthesis of a 20-deoxybryostatin by a RCM wa

(Chemical Equation Presented) A total synthesis of the naturally occurring hydroxy ketone PEIPC 1, a compound that plays a role in endothelial activation in atherosclerosis, has been completed via a triply convergent preparation of a protected EI derivative 13 from 3,5-diacetoxycyclopentene 7, pentane-1,5-diol, and vinyllithium, using Sharpless epoxidation and enzymatic resolution as key steps. Final coupling with lyso-PC 16 and silyl group deprotection gave PECPC 2 and PEIPC 1, which showed the same activity as natural PECPC and PEIPC.

Asymmetric total synthesis of phytotoxic nonenolide herbarumin III was accomplished by a chemoenzymatic approach. The main highlight of the synthesis was to fix the hydroxyl stereocenters (C7 and C9) by lipase catalyzed irreversible transesterification.
Synthesis of phosphorylcholines possessing 5,6- or 14,15-epoxyisoprostane A2 at sn-2 position
Acharya, Hukum P.,Kobayashi, Yuichi
, p. 8435 - 8438 (2007/10/03)
Use of the PMBOCH2 group (PMB: p-MeOC6H 4CH2) as a substitute of CO2H provided high level of reproducibility and efficiency in construction of the full structure of 5,6-epoxyisoprostane A2.
The biomimetic construction of fused cyclic polyethers
Hayashi, Nobuyuki,Fujiwara, Kenshu,Murai, Akio
, p. 12425 - 12468 (2007/10/03)
The formation of fused cyclic ethers by biomimetic synthesis was demonstrated. The one-pot successive ring-expansion reactions of bromo diepoxides were investigated by regarding the epoxy groups as the nucleophiles for the intramolecular cationic carbons to obtain the fused cyclic ethers.
Synthesis of a Novel Acetylenic Ester, Methyl (E)-5-Octadecen-7,9-diynoate

, p. 2001 - 2009 (2007/10/02)
We, herein, report synthesis of methyl ester of (E)-5-octadecen-7,9-diynoic acid, one of the novel acetylenic fatty acids of Paramacrolobium caeruleum root bark with unique biological activity, by coupling synthesized C1 to C8 fragment with 1-decyne.
