Recent progress in Lewis acid–Lewis base bifunctional asymmetric catalysis*
Two enantioselective cyanation reactions, the Strecker reaction of ketoimines and the Reissert reaction of pyridine derivatives, promoted by Lewis acid–Lewis base bifunctional asymmetric catalysts are described.
متن کاملTransmetalation Reactions Producing Organocopper Reagents
Organocopper reagents constitute a key class of organometallic reagents, with numerous applications in organic synthesis [1]. Their high reactivities and chemoselectivities have made them unique intermediates. Most reports use organocopper reagents of type 1 or 2, which are prepared from organolithiums. This transmetalation procedure confers optimal reactivity, but in many cases it permits only...
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...
متن کاملRecent Progress in Zeolite/Zeotype Membranes
This is a comprehensive review of the recent progresses made in the field of zeolite membranes. It describes zeolitic materials and methods of membrane fabrication, followed by a summary of applications for gas separation, pervaporation and separation of liquid mixtures. Special attention is called to polymer mixed matrix membranes (MMMs) and membranes based on metal organic frame works (MOFs)....
متن کاملOrganocopper Reagents for the Synthesis of Saturated, and -ethylenic Aldehydes and Ketones
Conjugate addition of organocopper reagents to ct,-ethylenic aldehydes is discussed. Use of cz,r3-ethylenic aminals is an— other approach to the same target, namely homologation of R-M to an aldehyde with three more carbon atoms. The c,-ethylenic aldehydes are easily prepared by carbocupration of c,13-acetylenic acetals. A new way to cz,t3-ethylenic ketones, mediated by organo copper reagents i...
