An efficient synthesis of the C1C6 aliphatic fragment 3 and its coupling to the C7C19 fragment 4 of kabiramide C is described. Key transformations include a TiCl4 promoted condensation between aldehyde 5 and crotylsilane (R)-6 and a Barton-McCombie deoxygenation of the homoallylic alcohol 9 to set the stereochemical array.
