developed for the rapid assembly of anti-homoallylic alcohols with high levels of regioselectivities (>20:1), diastereoselectivities (up to >20:1), and yields (up to 91%). The allylation was realized through a crucial π-allylnickel intermediate, which was obtained via insertion of allenes with a Ni–H intermediate. Moreover, γ,γ-disubstituted homoallylicalcohols with a quaternary stereocenter can also be prepared

trifluoromethylthioesters from aldehydes. This reaction is mild, highly selective, operationally simple, works under redox neutral condition, and exhibits a broad substrate scope with high functional group tolerance. The synthetic utility of this method is demonstrated by the late-stage functionalization of bioactive molecules, making it amenable for drug discovery.

The present disclosure is in the field of biomedical, pharmaceutical and polymeric sciences. The present disclosure relates to the conjugates of pendant polymers capable of forming guest:host complexes or covalent/non-covalent conjugates with cyclodextrins (or their derivatives), corresponding method of preparation and their application in treating lipid storage disorders. These conjugates possess improved properties including but not limiting to prolonged duration of action in cell and increased efficacy in removal of cholesterol from cells.
Development of a Low Toxicity, Effective pDNA Vector Based on Noncovalent Assembly of Bioresponsive Amino-β-cyclodextrin:Adamantane–Poly(vinyl alcohol)–Poly(ethylene glycol) Transfection Complexes

main chain polymer bearing poly(ethylene glycol) (MW 750) (PEG) or MW 2000 PEG and acid-labile adamantane-modified (Ad) grafts through an acid-sensitive benzylidene acetal linkage. These components were investigated for their ability to promotesupramolecular complex formation with pDNA using two different assembly schemes, involving either precomplexation of the pendent Ad-PVA-PEG polymer with the cationic
