合成路线1
The cyclization of piperidine-2-carboxylic acid ethyl ester (I) with aziridine (II) in ethanol gives perhydropyrido[1,2-a]pyrazin-1-one (III), which is reduced with LiAlH4 to yield perhydropyrido[1,2-a]pyrazine (IV). The reaction of (IV) with NaNO2/HCl, followed by reduction with LiAlH4, affords perhydropyrido[1,2-a]pyrazin-2-amine (V), which is finally condensed with rifamicin SV-3-carbaldehyde (VI).
