Product structure and proposed mechanism of reaction catalysed by PvHVS from geranylgeranyl diphosphate (GGPP). (a) Product determined by NMR to be 11‐hydroxy vulgarisane. Green arrows indicate NOESY correlations supporting the assignment of relative stereochemistry. (b) Possible mechanism for cyclisation of GGPP into 11‐hydroxy vulgarisane, as previously proposed (Lou et al., 2014).
