Chemoenzymatic synthesis of 2-substituted 2-fluoro-1,3-dioxygenated chiral building blocks
摘要:
A series of 2-substituted-2-fluoro-1,3-dioxygenated chiral building blocks are synthesized via a chemoenzymatic route using either (i) lipase catalyzed monohydrolysis of suitably functionalized malonic diesters, or (ii) lipase catalyzed monoacetylation of suitably functionalized 1,3-propanediols.

The invention relates to compounds of formula (I), and their use as herbicides. In said formula, R1 to R9 represent groups such as hydrogen, halogen or organic groups such as alkyl, alkenyl, alkynyl, or alkoxy; X is a bond or a divalent unit; Y is hydrogen, cyano, hydroxyl or a linear or cyclic organic group. The invention further refers to a composition comprising such compound and to the use thereof for controlling unwanted vegetation.
