## Abstract Glycosyl __ortho__‐alkynylbenzoates have emerged as a new generation of donors for glycosidation under the catalysis of gold(I) complexes such as Ph~3~PAuOTf and Ph~3~PAuNTf~2~ (Tf=trifluoromethanesulfonate). A wide variety of these donors, including 2‐deoxy sugar and sialyl donors, are
