Singh, Govind P. published the artcileAchiral 2-Hydroxy Protecting Group for the Stereocontrolled Synthesis of 1,2-cis-¦Á-Glycosides by Six-Ring Neighboring Group Participation, Application of 2,4,6-Trimethoxybenzenethiol, the publication is Organic Letters (2015), 17(17), 4376-4379, database is CAplus and MEDLINE.
Glycosylation of a fully armed donor bearing a 2-O-(trimethoxybenzenethiol) Et ether protecting group is completely ¦Á-selective with a range of carbohydrate alc. acceptors. Low-temperature NMR studies confirm the intermediacy of cyclic sulfonium ion intermediates arising from six-membered ¦Â-sulfonium ring neighboring group participation. Selective protecting group removal is achieved in high yield in a single operation by S-methylation and base-induced ¦Â-elimination.
