For millions of years, plants evolve plenty of structurally diverse secondary metabolites (SM) to support their sessile lifestyles through continuous biochemical pathway innovation. While new genes commonly drive the evolution of plant SM pathway, how a
From the results obtained when nine insecticides and ten herbicides were applied at a series of dosages to soil infested to various degrees with P.K. & B. it was found possible to separate these chemicals into four groups on the basis of... LT Richardson - 《Canadian Journal of Plant Sci...
78% yield as a single diastereoisomer. Removal of theO-MOM andN-Boc groups and subsequent cyclization proceeded smoothly by simply stirring a dichloromethane solution of43in the presence of trifluoroacetic acid (TFA) to afford, after work-up with aqueous NaHCO3solution, the (-)-sinoracutine (...

b Kinetics of p-NPP hydrolysis into p-nitrophenol catalyzed by lipase-loaded crosslinked colloidosomes (red plot), lipase-loaded non-crosslinked colloidosomes (blue plot), and free lipase (black plot). The loaded lipase for all groups was 0.005 mg. Error bars indicate the SD of three ...
The method can be employed to synthesize a wide range of target compounds and to introduce different functional groups into the β-aminoketone skeleton. Additionally, the method consistently has the advantages of good yields, short reaction time, and simply experimental workup procedure, which makes...
