合成路线1
该中间体在本合成路线中的序号:(XXXII)The reaction of tosylate (XXV) with potassium ethylxanthate (XXIX) gives the adduct (XXX), which is cyclized with 3-methoxy-2-methyl-2-propenal (XXI) by means of t-BuOK, NH4Cl and NH3 in THF yielding the dihydropyridine (XXXI). The oxidation of (XXXI) with MCPBA in chloroform affords the pyridine (XXXII), with simultaneous formation of the sulfinyl group. Finally, this compound is cyclized with 4-methoxyphenylene-1,2-diamine (XXXIII) by means of TFA in refluxing toluene.
