Abstract
A synthetic strategy for all aldohexoses with individually addressable protecting groups from dihalomethane C1-units is reported. The underlying synthesis of C6-sugar alcohols relies on three consecutive Matteson sequences, vinylation and bishydroxylation. Erythro and threo isomers have been realized for every glycol motif by strategic variation of the sequence.

Abstract
Nucleic Acid Therapeutics (NATs) are establishing a leading role for the management and treatment of genetic diseases following FDA approval of nusinersen, patisiran, and givosiran in the last 5 years, the breakthrough of milasen, with more approvals undoubtedly on the way. Givosiran takes advantage of the known interaction between the hepatocyte specific asialoglycoprotein receptor (ASGPR) and N-acetyl galactosamine (GalNAc) ligands to deliver a therapeutic effect, underscoring the value of targeting moieties. In this review, we explore the history of GalNAc as a ligand, and the paradigm it has set for the delivery of NATs through precise targeting to the liver, overcoming common hindrances faced with this type of therapy. We describe various complex oligosaccharides (OSs) and ask what others could be used to target receptors for NAT delivery and the opportunities awaiting exploration of this chemical space.

Abstract
This review discusses the challenges facing research in 'functional glycomics' and the novel technologies that are being developed to advance the field. The structural complexity of glycans and glycoconjugates makes studies of both their structures and recognition difficult. However, these intricate structures can be captured from their natural sources, isolated and fluorescently-tagged for detailed structural analysis and for presentation on glycan microarrays for functional recognition by glycan-binding proteins. These advances in glycan preparation and manipulation enable the streamlining of functional glycomics studies and will help to propel the field forward in studying natural, biologically relevant glycans.

Abstract
Carbohydrates are the basis for many therapeutic and diagnostic strategies, yet the full potential of glycans in medicine has not been realized. The study of the precise role of different carbohydrates, bound to either proteins or lipids, is hampered by difficulties in accessing pure, well-defined glycoconjugates. This Review highlights recent advances in glycobiology with a particular emphasis on oligosaccharide synthesis and conjugation techniques for the construction of homogeneous glycoconjugates. New methods for the study of protein-glycan interactions such as carbohydrate arrays and in vivo visualization of glycosylation pattern changes will also be addressed. The development of glycotherapeutics is just beginning, and much remains to be understood about the relationship between glycoconjugate structure and function. The emergence of novel tools will certainly facilitate and expand the use of carbohydrates in therapeutics and diagnostics.

Abstract
Carbohydrate arrays (glycoarrays) have recently emerged as a high-throughput tool for studying carbohydrate-binding proteins and carbohydrate-processing enzymes. A number of sophisticated array platforms that allow for qualitative and quantitative analysis of carbohydrate binding and modification on the array surface have been developed, including analysis by fluorescence spectroscopy, mass spectrometry and surface plasmon resonance spectroscopy. These platforms, together with examples of biologically-relevant applications are reviewed in this Feature Article.
