The first synthesis of lacto-N-hexaose (LNH) has been completed using a convergent strategy. The donor-acceptor protecting-leaving group combinations were found to be of paramount significance for achieving successful glycosylations and minimizing side reactions. Lacto-N-tetraose, another common human milk oligosaccharide, was also obtained en route to the target LNH.
