Participants

Reaction Steps

In the fourth step, a 0.4M solution of osmium tetroxide (0.05 mole for each mole of XI) is added dropwise to a solution in tetrahydrofuran of the intermediate (XI) and 4-methylmorpholine-4-oxide monohydrate (two moles for each mole of intermediate) and the resulting mixture stirred for 16 to 20 hours to obtain the 3-(2,3-dihydroxypropyl)imidazolidinone intermediate (XII) in the reaction mixture which may then be recovered employing conventional procedures.
