## Abstract We have synthesized a tetrasaccharide containing a 3,4‐dibranched L‐__glycero__‐D‐__manno__‐heptose (Hep), β‐lactosyl‐(1⇄4)‐[L‐α‐D‐Hep‐(1⇄3)]‐L‐α‐D‐Hep **19**, by using a mannose (Man) derivative as an acceptor. Prior to the construction of the branched Hep, we confirmed that the 3,4‐di
