Figure presented Enantioselective acylation catalyzed by the thioamide modified 1-methylhistidine methyl ester 1 in combination with DABCO-mediated racemization of the substrate led to the efficient dynamic kinetic resolution of meso-1,2-diol monodichloro

The cleavage of ethylene, propylene, and cyclohexene oxides by protic acids RCOOH (R= CH3, CF3) in the presence of sources of nucleophilic anions (the lithium or tetrabutylammonium salts of perchloric or substituted sulfonic acids) leads to the formation not only of 2-hydroxyalkyl carboxylates but also of significant amounts of 2-hydroxyalkyl perchlorates and sulfonates.In the reactions of the same oxides with nitronium fluoroborate and the above-mentioned salts in methylene chloride 2-perchloryl- and 2-sulfonyloxyalkyl nitrates are formed with high yields; these are the products from opening of the epoxide ring and subsequent combination of the perchlorate and substituted sulfonate ions.The investigated processes extend the range of reactions involving the concurrent combination of nucleofugic anions and can be used as a method for the production of β-hydroxy- and β-nitroxyalkyl perchlorates and sulfonates.

Oxidative displacement of iodine from primary alkyl iodides and vic-substituted iodocyclohexanes with m-chloroperbenzoic acid in either dichloromethane or t-butyl alcohol-water gives primary alcohols and vic-substituted cyclohexanols, respectively.Retention of configuration at the displacement centre occurs for all of the trans-vic-substituted iodocyclohexanes except the iodoacetate and iodotrifluoroacetate where inversion of configuration occurs to give cis-hydroxy-esters.Oxidation of (S)-2-iodo-octane occurs with almost complete inversion to give (R)-octan-2-ol but also affords octan-1-ol, octan-3-ol, and octan-2-one.
