Abstract
Ready cyclization through silica gel chromatography of the asymmetric phenolic lactaldehyde (14) afforded the diastereomeric pair of isochroman-4,7-diols (21) and (23) in good yield, while (17), the benzylic epimer of (14), similarly yielded the isochroman-4,7-diol (25) as a single diastereomer.Keywords: Asymmetric synthesis; isochromandiols; lactaldehyde cyclization.
