The first completely enantioselective syntheses of indicine N-oxide, intermedine N-oxide, and their enantiomers have been achieved stereospecifically. A synthetic analogue modeled on indicine N-oxide showed the superior activity to indicine N-oxide itself against cancer cell in vitro test.

Indicine N-oxide (1), a pyrrolizidine alkaloid potentially useful for an anticancer drug was synthesized in the natural form through regioselective coupling of (+)-retronecine (2) and the protected necic acids 16a and 16b, the latter being efficiently prepared from the optically pure lactone 5.
