✦ Synopsis

The syntheses of several naturally occurring molecules, substituted 2-trimethylsilylfurans to but-2-en-4-olides. A subsequent intramolecular Michael addition procedure was namely prehispanolone, sphydrofuran, secosyrins, and syringolides are reviewed. Interestingly, these compounds also essential in the construction of the spiro skeleton. Two significant issues concerning regioselectivity and are all structurally related, possessing a 1,7dioxaspiro[4.4]nonane framework. The pivotal step in these stereoselectivity are also addressed. synthetic endeavors involves the peracid oxidation of turally intriguing secondary metabolite produced by acti- [a] Department of Chemistry, The Chinese University of Hong be seen, these molecules all possess stereochemical features Kong, Shatin,
