合成路线1
该中间体在本合成路线中的序号:(XVII)Wittig reaction of lactol (XIII) with the ylide generated from phosphonium salt (XIV) and potassium tert-butoxide afforded acid (XV), which was subsequently esterified with isopropyl iodide and DBU to give the isopropyl ester (XVI). Cleavage of the tetrahydropyranyl ethers of (XVI) under mildly acidic conditions followed by HPLC separation using a chiral column provided the desired alcohol diastereoisomer (XVII). Finally, hydrolysis of ester (XVII) under basic conditions provided the corresponding free acid.
