The combination of ring closing metathesis and beta-fragmentation offers an efficient entry into (Z)-configured medium ring cycloalkenes. The fragmentation step can be effected under anionic or radical conditions. The versatility of this method is demonstrated by the total synthesis of (+/-)-periplanone C-a macrocyclic pheromone of Periplaneta americana.
Indium promoted allylation of carbonyl compounds with 4-(bromomethyl)-1,3-dioxol-2-one diastereoselectively affords anti-α,β-dihydroxyketones, protected as enol carbonates. These initial products can be deprotected to free dihydroxyketones or transformed under mild conditions into the corresponding cyclic carbonates, which constitutes a useful approach to(More)
BACKGROUND/AIMS 5-Ketoximeisosorbide-2-mononitrate (50-IS-2-MN) was synthesized and its pharmacological and toxicological characteristics were examined and compared with its parent drug, isosorbide-5-mononitrate (IS-5-MN, CAS 16051-77-7), and its diastereoisomer 2-ketoximeisosorbide-5-mononitrate. METHODS Vasorelaxation was studied on(More)
The transformation of isosorbide-5-mononitrate (CAS 16051-77-7, IS-5-MN) to the corresponding keto derivative and its ketoxime (oxime-nitrate derivative of isosorbide) is described. The effects of IS-5-MN and the new oxime-nitrate (ON) on the endothelial and smooth muscle cells of isolated rings of the rat superior mesenteric artery were examined. After(More)
