Standard Protocols for Chemical Synthesis of Glycan Core-Amino Acids *

Goals: The project supported by National Institute of General Medical Sciences (U01GM116263) aims to develop facile core synthesis-enzymatic extension strategy to access diverse O-glycans and O-glycopeptides. Convergent synthetic routes were developed to access milligram to gram scales of O-Glycan Core structures linked with Ser or THr, including O-GalNAc Core 1-8, O-Mannosyl Core m1, m2, etc. Standard operation procedure (SOP) were generated and listed. 

O-GalNAc Core
O-Man Core
O-Fuc Core
Coming soon......
