The present invention relates to a cycloaddition process comprising the step of reacting a halogenated aliphatic 1,3-dipole compound with a (hetero)cycloalkyne according to Formula (1): Preferably, the (hetero)cycloalkyne according to Formula (1) is a (hetero)cyclooctyne. The invention also relates to the cycloaddition products obtainable by the process according to the invention. The invention further relates to halogenated aliphatic 1,3-dipole compounds, in particular to halogenated aliphatic 1,3-dipole compounds comprising N-acetylgalactosamine-UDP (GalNAc-UDP), and to halogenated 1,3-dipole compounds comprising (peracylated) N-acetylglucosamine (GlcNAc), N-acetylgalactosamine (GalNAc), N-acetylmannosamine (ManNAc) and N-acetyl neuraminic acid (NeuNAc).
本发明涉及一种环加成工艺,包括卤代脂肪族 1,3-二极化合物与符合式(1)的(杂)环炔反应的步骤:根据式(1)的(杂)环炔最好是(杂)环辛炔。本发明还涉及根据本发明的工艺可获得的环加成产物。本发明还涉及卤代脂肪族 1,3-二极化合物,特别是包含 N-乙酰半乳糖胺-UDP(GalNAc-UDP)的卤代脂肪族 1,3-二极化合物、以及由(过酰化)N-乙酰葡糖胺(GlcNAc)、N-乙酰半乳糖胺(GalNAc)、N-乙酰甘露糖胺(ManNAc)和 N-乙酰神经氨酸(NeuNAc)组成的卤代 1,3-二极化合物。
