Heteromultimetallic complexes consisting of three Co(II) ions and one lanthanide ion were synthesized and applied to the alternating copolymerization of CO2 and cyclohexene oxide. Unlike the conventional cobalt(III) salen complexes, the high thermal stability of the present catalyst allowed us to reach a turnover number of 13000, one of the highest values ever reported for multimetallic systems.

2-(1-Adamantylimino)-5-methyl-1,3-oxathiolane 1 was synthesised from the reaction between adamantan-1-ol and 1-thiocyanopropan-2-ol in sulphuric acid. Compound 1 undergoes ring opening followed by elimination to afford novel adamantane alkoxyureas 3 a-d and 5 a, b with a number of oxyamino nucleophiles 2 a-d and 4 a, b.

We report the first example of syntheticchondroitinsulfate (CS) microarrays to rapidly identify glycosaminoglycan−protein interactions and probe the specificity of proteins for distinct sulfation sequences. Using the microarrays, we identify a novel interaction between CS and TNF-α, a proinflammatory cytokine involved in rheumatoid arthritis, Crohn's disease, and psoriasis. Moreover, we demonstrate
