A non-aesthetic post-abdominoplasty umbilicus is known to be a significant concern for many patients who consider this procedure, due to its central and visible location. The goal of this method is to minimize the visible scar and create a natural-looking and aesthetically pleasing umbilicus. In this multimedia article, we illustrate our technique that is both reproducible and easy to perform. It produces a scarless caudal aspect, pleasant depth, and natural superior hooding appearance to the post-op umbilicus. Limitations of this technique are discussed.

Naphtho[2,3b]thiophene is a linear sulfur containing polycyclic aromatic hydrocarbon. Naphtho[2,3b]thiophene and its derivatives are commonly accessed by a Bradsher cyclization. Synthesis of the Bradsher cyclization substrate typically requires harsh conditions, including several oxidation state changes. Here we report an improved, multigram synthesis of 3-bromonaphtho[2,3b]thiophene, exploiting a copper-catalyzed cross coupling to prepare the Bradsher substrate in 3 steps from commercial materials while minimizing redox reactions. Modification of the naphthothiophene scaffold in the 3-position has not previously been reported. In this work, the 3-bromonaphthothiophene is further functionalized via lithium-halogen exchange, with the key finding being a specific order of addition in lithiation is required to avoid undesired rearrangement reactions. Transformation to a versatile set of derivatives, including a naphthothiophene-containing chiral amine is illustrated.
