Abstract: We report highly β-selective bis-thiourea-catalyzed 1,2-cis-O-pyranosylations employing easily accessible acetonide-protected donors. A wide variety of alcohol nucleophiles, including complex natural products, glycosides, and amino acids were β-mannosylated and rhamnosylated successfully using an operationally simple protocol… read more here.
