Ortho substituted trans 2,3-diaryloxiranes afforded the corresponding syn glycols stereo- and enantiospecifically. Stereoselectivity appears related to the coordination ability of the substituents, irrespective of their electronic properties. Indeed o-OCH3 and o-OBn substituted syn glycols are obtained in high stereochemical ratios (6/1 and 10/1 respectively), and o-OTIPS and o-NO2 substituted ones are obtained as exclusive products, with the same ee of the parent epoxides.

The use of KF and I2 at 80 °C in 1,4-dioxane furnishes iodinated compounds in high yields.
