Ester cleavage by S,S-(+)-tetrandrine derivative bearing thiol groups
A chiral cyclophane–type macrocycle bearing two thiol groups has been prepared by chemical modification of S,S-(+)-tetrandrine. Cleavage of p-nitrophenyl acetate by deprotonated form of this macrocycle proceeds with a rate constant expected for a simple thiol anion of similar basicity, but the reactivity toward p-nitrophenyl esters of N-protected amino acids is one order of magnitude higher tha...
متن کاملSynthesis and photooxidation of styrene copolymer bearing camphorquinone pendant groups
(±)-10-Methacryloyloxycamphorquinone (MCQ) was synthesized from (±)-10-camphorsulfonic acid either by a known seven-step synthetic route or by a novel, shorter five-step synthetic route. MCQ was copolymerized with styrene (S) and the photochemical behavior of the copolymer MCQ/S was compared with that of a formerly studied copolymer of styrene with monomers containing the benzil (BZ) moiety (an...

Recently, the transition metal-catalyzed cycloisomerization has attracted much attention, because it can provide useful cyclic compounds from readily available starting materials and produce different cyclic compounds from the same substrate, depending on the catalyst and reaction conditions. One of the most studied substrates are 1,6-enynes. The transition metalcatalyzed cycloisomerization of ...
متن کاملDesigning High-Refractive Index Polymers Using Materials Informatics
A machine learning strategy is presented for the rapid discovery of new polymeric materials satisfying multiple desirable properties. Of particular interest is the design of high refractive index polymers. Our in silico approach employs a series of quantitative structure–property relationship models that facilitate rapid virtual screening of polymers based on relevant properties such as the ref...
