Zusammenfassung:
An indirect yet highly efficient protocol for the β-d-mannosylation of sterically hindered alcohols is reported. Trichloroacetimidate 5 is used a key building block which is converted into the desired mannosides 9 via triflates 8 by an ultrasound promoted β-d-gluco → β-d-manno inversion process.
