标题:Method for preparing intermediates for the synthesis of steroid side chains in optically active form
发明人：DELUCA HECTOR F; SCHNOES HEINRICH K; PERLMAN KATO L

摘要:This invention provides a novel method for the preparation of optically active arylalykylsulfone derivatives, having a chiral center in the alkyl moiety in either the (R)- or the (S)-configuration. These optically active sulfones find use in the stereospecific synthesis of steroid or vitamin D compounds having chiral center at either carbon 24 or carbon 25 of the side chain. The method comprises the steps of reacting an optically active sulfinate ester having a chiral center at sulfur with a racemic alkyl Grignard reagent to obtain a mixture of diastereomeric sulfoxides, separating the mixture of diastereomeric sulfoxides, and oxidizing separately each of the diastereomers to obtain the desired optically active sulfone.

标题 :Methods for synthesis of end-functionalized polyolefins

摘要:A strategy for the synthesis of semi-telechelic polyethylene through the palladium diimine-catalyzed chain transfer polymerization of ethylene using various silanes as chain transfer agents is reported. Polymer molecular weight and end-group chemical structure can be tuned by varying the chain transfer agent as well as its concentration. NMR spectroscopy confirms that the silicon of the chain transfer agent is incorporated into the polymer. The stability of the catalyst toward polar monomer enables the chain transfer polymerization of semi-telechelic poly(ethylene-methyl acrylate) copolymers.
