Reaktionsschritte
was prepared in analogy to example 39, but using in the aldol-coupling step ethyl isopropoxy-acetate instead of butyl butoxy-acetate as white crystals of mp. 148-150°. The former reagent was synthesized as described above for but-3-enyloxy-acetic acid (see example 65) from iPrOH, NaH, and bromo-acetic acid, followed by acid catalyzed esterification with EtOH.
