合成路线1
该中间体在本合成路线中的序号：(XVba)In a related method, 4-(2-bromoethoxy)benzaldehyde (XI) was subjected to a Horner-Emmons reaction with phosphonate (II) to produce the unsaturated ester (XIIa-b), which was further hydrogenated to afford (XIII). Alkylation of phenoxazine (XIV) with bromide (XIII) gave adduct (VIII) (1,2). In a different reaction sequence, bromoaldehyde (XI) was initially condensed with phenoxazine (XIV), producing adduct (XV). This was subjected to Horner-Emmons condensation with (II) to give the unsaturated ester (XVIa-b), which was then hydrogenated to (VIII). Alternatively, double-bond reduction of (XVI) by means of Mg in MeOH gave rise to the transesterified methyl ester (IX). Ester hydrolysis as above provided acid (X).
