Auxotrophic mutants have played an important role in the genetic dissection of biosynthetic pathways in microorganisms. Equivalent mutants have been more difficult to identify in plants. The bio1 auxotroph of Arabidopsis thaliana was shown previously to be defective in the synthesis of the biotin
The reactivity of 2-alkynylbenzoic acids toward Lawesson's reagent (LR) under microwave irradiation (300 W, 100 °C, CH2 Cl2 ) was assessed. It was found that, depending on reaction conditions, either a dithionation- or a monothionation-cycloisomerization process takes place
