    • The reaction of the imidazolide derived from acids 10 and fragment D (9) required higher temperatures and longer reaction times as the size of the alkyl groups α to the C-5 carbonyl increased. Toluene was used as solvent for the preparation of 10d

    • The diastereomeric mixtures of epoxides 15 were isolated in 80-90% yields. The overall yields of chlorohydrins 2 are based on the amount of pure desired diastereomer obtained after chromatography
