A directed screen of a relatively small number of compounds, selected for kinase ATP pocket binding potential, yielded a novel series of hit compounds (1). Hit explosion on two binding residues identified compounds 27 and 43 as the best leads for an

Polyamino acid-catalysed asymmetric epoxidation: Sodium percarbonate as a source of base and oxidant
Publikováno v:
Tetrahedron Letters. 40:5417-5420
New reaction conditions, using sodium percarbonate, are reported for the polyamino acid-catalysed asymmetric epoxidation of enones. Under these new conditions the rate of the uncatalysed reaction is reduced allowing an increased ratio of substrate to

The design and synthesis of a structural motif which can mimic protein-protein interactions is described. These moieties, termed asdendroids (Greekdendron, a tree), are low-molecular-weight structures which are based on self-organising dendritic poly

The asymmetric oxidation of some enones (Table 1), selected dienones 3–5, and a trienone 13 is accomplished using poly-L-leucine or poly-D-leucine and urea hydrogen peroxide under non-aqueous conditions. One of the resultant epoxy ketones 6 has bee

Ligands containing an enantiomerically pure oxazoline and a sulfur-containing tether have been examined for their ability to provide asymmetric induction in palladium catalysed allylic substitution reaction. The enantioselectivity obtained was found

A series of enantiomerically pure oxazolines tethered to alcohols have been prepared. The use of these oxazolines has been demonstrated in the catalysed addition of diethylzinc to aromatic aldehydes to afford the corresponding secondary alcohols with
