We report the synthesis and potencies of several selective S1P4 receptor agonists. Sphingosine-1-phosphate (S1P) is a biologically active lysophospholipid with the capacity to induce a broad range of cellular responses via its interaction with

A modified Weix's reductive coupling for alkylation of amidoaryl bromides based on Ni(COD)2 precatalyst and 2,2′-dipyridyl ligand was developed. This reaction is reliable for amidophenyl bromides and gives yields up to 87%, and is potentially useful in the synthesis of amidophenyl-containing molecules.
Highly active catalyst for the heterogeneous Suzuki-Miyaura reaction: Assembled complex of palladium and non-cross-linked amphiphilic polymer

An assembled insoluble catalyst, PdAS, prepared from palladium ((NH 4)2PdCl4 (1)) and non-cross-linked amphiphilic copolymer poly(N-isopropylacrylamide-co-4-diphenylstyrylphosphine) (2) was developed. It was found that PdAS is an excellent catalyst for the Suzuki-Miyaura reaction on three points: (1) The use of 8 × 10 -7 to 5 × 10-4 mol equiv of PdAS afforded the coupling products efficiently after easy workup, with the turnover number reaching up to 1 250 000. (2) The catalyst was reusable many times without loss of catalytic activity. (3) PdAS showed good stability in any reaction medium (i.e., water or aqueous or anhydrous organic solvents). Analytical study of PdAS indicates that the phosphines in 2 coordinate to palladium to form PdCl2(PPh2Ar)2 species.
