Biosynthesis of Cyclopropane Compounds
Oleic acid was converted to dihydrosterculic acid (9,10methyleneoctadecanoic acid) by Lactobacillus arabinosus cells. This was established by the mass spectra of branched chain esters formed by reductive opening of the cyclopropane ring of the corresponding cyclopropane fatty esters. The mass spectra allowed unambiguous assignment of the ring location to position 9,10. Oleic acid-9,10-d2 was co...
متن کاملBiosynthesis of Cyclopropane Compounds
Several natural and synthetic phospholipids can serve as substrates for the cyclopropane synthetase enzyme of Closfridium bufyricum. The conditions for optimum substrate effectiveness vary with the substrate; e.g. an anionic surfaceactive agent is necessary with phosphatidylethanolamine, while divalent cations stimulate the rate of reaction with anionic phospholipids. These variable conditions ...
متن کاملRing-expansion reaction of oximes with aluminum reductants.
The ring-expansion reactions of heterocyclic ketoximes and carbocyclic ketoximes with several reductants such as AlHCl2, AlH3 (alane), LiAlH4, LiAlH(OtBu)3, and (MeOCH2CH2O)2AlH2Na (Red-Al) were examined. Among reductants, AlHCl2 (LiAlH4:AlCl3 = 1:3) in cyclopentyl methyl ether (CPME) has been found to be a suitable reagent for the reaction, and the rearranged cyclic secondary amines were obtai...
متن کاملRing expansion of vinylaziridines through the strain-release pericyclic reaction: recent developments and applications.
Recent syntheses of azetidines, pyrrolidines, piperidines and azepines through cycloaddition or sigmatropic rearrangements of vinylaziridines are described. Applications to natural product synthesis and mechanistic investigations are also summarized.
متن کاملRecent Progress in Allergen Immunotherapy
The efficacy of allergen immunotherapy for the treatment of allergic rhinoconjunctivitis with or without seasonal bronchial asthma and anaphylaxis caused by the sting of the hymenoptera class of insects has been clearly demonstrated in numerous well-designed, placebo-controlled trials. Immunotherapy whether by subcutaneous injection of allergen extract or by oral/sublingual routes modifies peri...
