摘要:The enantiomers of amino acid benzyl esters are very important synthetic intermediates. Many of them are currently prepared by treatment with benzyl alcohol and p -toluenesulfonic acid in refluxing benzene or carbon tetrachloride, to azeotropically remove water, and then pre...

摘要:ABSTRACT(#br)The four positional isomers of nitrocatechol monobenzyl ether were prepared as intermediates to nitrobenzodioxanes directly from 2-benzyloxyphenol or, through two-four steps, from catechol. These preparations addressed the issue of the certain identification of the n...

摘要:Abstract(#br)Each of the four aromatic –CH= of ( S,R )-2-pyrrolidinyl-1,4-benzodioxane [( S,R )- 6 ] and of its epimer at the dioxane stereocenter ( S,S )- 6 , previously reported as α4β2 nAChR ligands, was replaced with nitrogen. The resulting four diastereoisomeric pairs o...

摘要:Abstract(#br)The simplest way to prepare the tosylate salts of amino acid benzyl esters, whose enantiomers are very important synthetic intermediates, is treatment of amino acid with benzyl alcohol and p -toluenesulfonic acid in a refluxing water-azeotroping solvent (Fischer...

摘要:Abstract(#br)Unlike the diastereomeric 1-phenylethylammonium salts, the diastereomeric N -1-phenylethylamides of ( S )- and ( R )-1,4-benzodioxane-2-carboxylic acid show significant differences in fusibility and solubility so as to be efficiently resolved by precipitation of the ...

摘要:Abstract(#br)A series of 3-nitrophenyl and 3-hydroxyphenyl ethers of ( S )- N -methylprolinol bearing bulky and lipophilic substituents at phenyl C5 were tested for affinity at α4β2 and α3β4 nAChRs. The two phenyl ethers 5-substituted with 6-hydroxy-1-hexynyl showed hig...

摘要:A one‐pot reductive amination of aldehydes and ketones with NaBH4 was developed with a view to providing efficient, economical and greener synthetic conditions. A recyclable iron‐based Lewis catalyst, Aquivion‐Fe, was used to promote imine formation in cyclop...
