Ring-opening allylation of cyclic acetals has required stoichiometric amounts of Lewis acids. In this paper, catalytic ring-opening allylation in the presence of silica-alumina is reported. This ring-opening allylation showed high atom economy. Consecutive allylation/hydrolysis using silica-alumina afforded homoallyloxyalcohols in good to high yields.

protein of interest to generate libraries of chimeric degraders, which are subsequently screened for effective protein degradation directly from cultured cells with a cytoblot assay. Our study exemplifies that this practical “preTACs-cytoblot” platform allows efficient PROTAC assembly and rapid activity assessments. It may help industrial and academic investigators to accelerate their streamlined development
The present invention relates to degradable polyacetal polymers having a C(O)-(CH2CH2O)n-R5 or a saccharide attached to amine radical of the backbone of the polymer, their polymer-active agent conjugates and their preparation processes, to compositions, and hydrogels containing them, as well as their use in therapy, diagnostic imaging and cosmetics.
