Rhodium catalysed hydrogenation of 3-methylene-1,2-diazetidines with a range of chiral ligands is reported. Using Mandyphos, excellent levels of chemo- and enantioselectivity (up to 89% ee) can be achieved. Reductive cleavage of the derived 3-substituted 1,2-diazetidine with LiDBB provides the enantioenriched biscarbamate protected 1,2-diamine.
OBJECTIVE Human milk (HM) is the ideal food for all newborns and infants. Apart from various bioactive compounds, including cytokines, antibodies, hormones, vitamines, it also contains polyamines, such as spermine (Sp), spermidine (Spd) and putrescine (Put). AIM The present study investigated polyamine metabolism in colostrum and mature human milk by measuring the polyamine oxidase (PAO) and ...
The oxidase activity of normal serum is due to the presence of the blue copper protein, ceruloplasmin. This is an a-globulin of molecular weight 151,000 containing 8 copper atoms per molecule (1). Its physiological substrate, if any, is unknown (2), but it has a weak oxidase activity for compounds that can be oxidized to quinone or quinone imines (3). The copper atoms in the protein appear to b...
Many effects of polyamines (PAs) are well known in plant developmental processes; however, the significance their catabolism is not understood. Copper amine oxidase (CuAO) involved degradation diamine putrescine (Put). The genotype dependence and time-dependent this enzyme rarely examined, so study aims to discover role CuAO tomato genotypes different stages seedling development. Exogenously ap...
