An efficientstereoselectivesynthesis of (+)-deoxoprosophylline from readily available p-anisaldehyde is described. Key steps in the synthesis include the stereoselective amination of anti-1,2-dibenzyl ether using chlorosulfonyl isocyanate, intermolecular olefination, and Pd-catalyzed intramolecular cyclization.

assignment by VCD methods is reported. Among them, compound RBM10-8 can irreversibly inhibit human sphingosine-1-phosphate lyase (hS1PL) while behaving also as an enzyme substrate. These findings, together with the postulated mechanism for S1PL activity, reinforce the role of RBM10-8 as a new mechanism-based hS1PL inhibitor.
Described herein are oxygen scavengers, oxygen scavenging polymeric compositions, and oxygen scavenging articles. The polymeric compositions comprising the oxygen scavengers may have utility in packaging, sealing, wrapping, and storing oxygen-sensitive substances, e.g., to preserve freshness of foods, beverages, and the like.

A polynnerizable composition including a late transition metal complex, a non-polar olefin, a polar olefin, and a free radical scavenger, wherein the polymerizable composition is capable of forming a linear poly[(non-polar olefin)-(polar olefin)] substantially free of free radical addition polymer, is disclosed. A method of copolymerizing a non-polar olefin with a polar olefin, catalyzed by a late transition metal complex in the presence of a free radical scavenger, to produce a linear poly[(non-polar olefin)-(polar olefin)] substantially free of free radical addition polymer is also disclosed.
