Iron(III)-salen complexes based on a chiral cis-2,5-diaminobicyclo[2.2.2]octane scaffold are used as catalysts for a variety of stereoselective reactions. High enantio- and diastereoselectivities can be achieved with these catalysts in sulfa-Michael conjugate addition to acyclic α,β-unsaturated ketones, in regioselective δ-addition of thiols to acyclic α,β,γ,δ-unsaturated ketones, and in Conia-ene carbocyclization of alkynyl-substituted β-dicarbonyl compounds The use of these chiral iron-salen complexes as catalysts provides a new method for conducting these three important reactions under environmentally sustainable conditions.

White, James D. published the artcileIron catalyzed enantioselective sulfa-Michael addition: a four-step synthesis of the anti-asthma agent Montelukast, SDS of cas: 162515-68-6, the publication is Chemical Science (2014), 5(6), 2200-2204, database is CAplus.

A salen ligand based on a chiral cis-2,5-diaminobicyclo[2.2.2]octane scaffold forms an iron(iii) complex with ferric chloride which catalyzed asym. addition of thiols to α,β-unsaturated ketones under mild conditions. The reaction (sulfa-Michael addition) produces β-thioketones in excellent yield and high enantiomeric excess from a wide range of aliphatic and aromatic thiols using chalcones and other conjugated enones as Michael acceptors. With α-substituted α,β-unsaturated ketones as acceptors, the addition showed strong preference (typically >50 : 1) for the syn diastereomer over the anti product. An asym. synthesis of (R)-Montelukast, the sodium salt of which is the com. anti-asthma drug Singulair, was devised using conjugate addition of a thiol catalyzed by our iron(III)-salen complex to an α,β-unsaturated ketone synthesized in a four-component, one-pot tandem Michael-aldol condensation. The reaction sequence to (R)-Montelukast proceeded in 72% overall yield over four steps from com. available materials. A mechanism for our catalyzed asym. sulfa-Michael addition was advance which coordinates the enone acceptor to the metal center of the iron-salen complex in an open lower quadrant under the bicyclic scaffold, thereby exposing only the si face of the double bond to attack by the external nucleophilic thiol. Prior internal coordination of the thiol to the metal center of the complex is proposed based on spectroscopic and chem. evidence and leads to activation of the catalyst through a trans ligand effect.

A practical route from oxetanes or thietanes to γ-(thio)butyrolactones via solvated-proton-assisted cobalt-catalyzed carbonylative ring expansion under syngas atm. were reported. A wide variety of γ-(thio)butyrolactones were afforded in a good to excellent yields. The versatility of this method were well demonstrated in the synthesis of intermediates towards the natural product Arctigenin as well as the pharmaceuticals Baclofen and Montelukast. The observed promoting effect of glycol ether solvent were rationally interpreted.

Rawat, Ajay Singh published the artcileSynthesis of Donepezil Hydrochloride via Chemoselective Hydrogenation, Related Products of quinuclidine, the publication is Organic Process Research & Development (2013), 17(12), 1617, database is CAplus.

A simple and highly chemoselective and cost-effective process for the synthesis of Donepezil 1 has been developed for com. production In the process, the exocyclic double bond is mainly targeted for catalytic hydrogenation in the presence of an N-benzyl group using sulfur, nitrogen, and phosphorous catalyst modifiers. In some cases, catalytic hydrogenation with Pd on charcoal also produced an undesired side product along with the main product due to over reduction Removal of these impurities by crystallization, column chromatog., or other means of purification makes the process tedious and lengthy, and sometimes it is difficult to achieve the impurity limit as per International Conference on Harmonisation (ICH) guidelines for active pharmaceutical ingredients. In the present investigation we report the synthesis of Donepezil 1 in pure form wherein the debenzyl impurity is within the acceptable limits.
