This Letter describes the synthetic routes to challenging pyridyl analogues of 2,3-dihydro-1,4-benzodioxin-6-carbaldehyde which were key intermediates for our antibacterial medicinal chemistry programme. All routes described started from kojic acid (8) and have been used to give multigram quantities of each aldehyde. (C) 2010 Elsevier Ltd. All rights reserved.
