In the presence of visible-lightphotoredox and chiral phosphate catalysts, a novel asymmetric Friedel–Crafts reaction of indoles and readily accessible α-amino acid derived redox-active esters is established to afford enantioenriched 1-indolyl-1-alkylamine derivatives in moderate to high yields and with high levels of enantioselectivities. This method not only shows a mild and efficient alternative

Using a novel water-soluble, active ester amide-containing functionalized controlled radical polymerization initiator, stimuli responsive polymers have been grown from the surface of a protein, exemplified by chymotrypsin or any protein having surface amino acids that will covalently bind to the active ester amide-containing functionalized initiator. It is shown that changes in temperature or pH can change the conformation of the polymer surrounding the enzyme, which in turn enabled the rational tailoring of enzyme activity and stability. This method has afforded an increase in the activity and stability of the enzyme by an order of magnitude at pH's where the enzyme is usually inactive or unstable. Multimodal temperature responsive protein-block copolymer conjugates are described.
