1-Aryl-2,2-dimethyl-1,3-propanediols as chiral auxiliares. Acetal formation with α,β-unsaturated aldehydes and analysis of the stereochemistry of cyclopropanation
Optically pure 1-aryl- (phenyl and 2-chlorophenyl) 1,3-propanediols, 1a and 1b, condense smoothly with aldehydes to provide the corresponding cyclic acetals 3.Except in cases that the aldehyde is substituted at the α-carbon atom, a single product is obtai
