and its (S)-isomer (7). Interestingly, AnaPT and CdpNPT introduced prenyl moieties from opposite sides of the indoline ring system. This feature was successfully used for the chemoenzymatic synthesis of four aszonalenin stereoisomers by using 6 and 7 as substrates and AnaPT and CdpNPT as catalysts. The stereoselectivity of the one-step reactions was about 100% and the conversion rates reached 85–100%
