Versuchsvorschrift
Following the procedure described for the preparation of 8-oxo-2,2-dimethyl-7α and β-(1-hydroxyethyl)-3-oxa-1-azabicyclo [4.2.0] octane from 8-oxo-2,2-dimethyl-3-oxa-1-azabicyclo [4.2.0] octane and using 1-(2-tetrahydropyranyl)-4-[2-(2-tetrahydropyranyl)oxyethyl]-2-azetidinone one obtains a diastereomeric mixture of both cis and trans-1-(2-tetrahydropyranyl)-3-(1-hydroxyethyl)-4-[2-(2-tetrahydropyranyl)-oxyethyl]-2-azetidinone.
