摘要：

An indirect yet highly efficient protocol for the P-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 beta-D-gluco --> beta-D-manno inversion process.
