    Many terpene glycosides exhibit contrasteric patterns of 1,2-diol glycosylation in which the more hindered alcohol bears a sugar; protection of the less hindered alcohol only increases steric repulsion. Here, we report a method for contrasteric glycosylation using a new sugar-linker that forms a cleavable, 10-membered ring with high efficiency, leading to syntheses of cotylenin E, J, and ISIR-050. Linker selection was aided by DFT calculations of side reactions and stereoselectivity, as well as conformational analyses using autoDFT, a Python script that converts SMILES strings to DFT-optimized conformational ensembles.
