A convergent synthesis of the dodecasaccharide scaffold of axinelloside A was achieved through Au(I)‐catalyzed [6+6] glycosylation. The initially devised [3+1+2] assembly of the nonreducing hexasaccharide fragment was low‐yielding, whereas a convergent [3+3] glycosylation under Au(I) catalysis was proven feasible, allowing for a semi‐gram scale preparation of the wanted hexasaccharide. The requisite 1,2‐
