[formula: see text] The kineticresolution of racemic epoxides via catalytic enantioselective rearrangement to allylicalcohols was investigated. Using the Li-salt of (1S,3R,4R)-3-(pyrrolidinyl)methyl-2-azabicyclo [2.2.1] heptane 1 as catalyst allowed both epoxides and allylicalcohols to be obtained in an enantioenriched form.

Abstract Acid-catalysed benzylidenation reactions of a series of alkyl substituted derivatives of cyclohexane- cis -1,2-diol have been studied. Preferential formation of the exo -phenyl benzylidene acetal was observed in the initial kinetic phase of the reaction of the 1- tert -butyl derivative, whereas the endo -phenyl acetal was preferentially formed from other diols. This behaviour has been rationalised
