Natural cis-solamin is a mixture of two tetra-epimeric diastereoisomers: biosynthetic implications for Annonaceous acetogenins.
The anti-tumour natural product cis-solamin has been shown to occur as a mixture two of tetra-epimeric diastereoisomers 1A and 1B, whereas solamin (6) was isolated as a single diastereoisomer; the biosyntheses of 1A/B and 6 are likely to involve enzyme-mediated cyclohydrations of the bis-epoxide acetogenins anti-diepomuricanin A2 and syn-diepomuricanin A1 respectively, where addition of water occurs regioselectively at either C15 or C20.
