Efforts towards a biomimeticsynthesis of the alkaloid pegaharmaline A began with attempted validation of the putative biosynthesis described in the isolation report. The reaction between vasicinone-derived pyrroloquinazoline 1 and tryptamines 2 and 9 proceeded under aqueous conditions at ambient temperature, forming the 1,6,10-triazaspiro[4.5]dec-7-anes 7 and 8.

The biotransformation of the anticholinergic quinazoline alkaloid Desoxypeganine is studied by means of aerobic incubation with the non‐induced supernatant obtained at 9000g from rabbitliver homogenates as enzyme source followed by an admixture of NADPH. The metabolites were identified by highperformance liquid chromatography, chemical ionisation mass spectrometry (LC‐CI MS) and electron impact mass
