Versuchsvorschrift
Synthesis of phenyl-thiazoles is described in Scheme 4. Reaction of benzyl or allyl alcohol with substituted 4-fluorobenzoic acid 1 afforded the substituted ether-benzoate 2. The substituted ether-benzoate 2 was then coupled with hydrazine to afford benzohydrazide 3. Reaction of benzohydrazide 3 with orthogonally protected amino acid 4 under HATU conditions followed by cyclization and deprotection (or vis versa) provided phenol 6 in good yield. Mitsunobu reaction of phenol 6 with desired alcohol followed by deprotection afforded the desired final compound 8. Reaction of the alcohol 8 with diethyl chlorophosphate followed by deprotection with TMSBr gave the corresponding phosphate.
