The reaction of the dihydroxy compound (XX) with Tbdms-Cl and imidazole gives the disilylated compound (XXI), which is deallylated by means of Pd(PPh3)4 to yield the 2-butenoic acid derivative (XXII). The reaction of (XXII) with the phosphoryl azide (XXIII) by means of TEA in benzene affords the butenoyl azide (XXIV), which is converted into the isocyanate (XXV) by heating in refluxing benzene. The reaction of (XXV) with 1,3-hexadienyl bromide (XXVI) by means of t-BuLi in THF provides the 2,4-heptadienoyl amide (XXVII), which is finally desilylated by means of HF and pyridine in THF to obtain the target Salicylihalamide A.
