    摘要: Polymer-based polyvalent malonic acid derivatives having anti-adhesive properties are described. The compounds comprise a polyamino acid linked to a group of formula (I). In formula (I), R.sup.1 and R.sup.2 together form a six-membered carbocylic or heterocyclic ring, containing at least one substituent selected from R.sup.4, R.sup.5, and R.sup.6. R.sup.3 is H, (CH.sub.2) .sub.m X or CH.sub.2 O(CH.sub.2).sup.m X.sup.1. The polyamino acid and the group of formula II are linked via R.sup.4, R.sup.5, or R.sup.6, or optionally via a spacer of formula --�Q.sup.1 --(CH.sub.2).sub.p --Q.sup.2 --!.sub.r.

    摘要: A process for the production of 2-alkyl-3-aroyl-5-nitrobenzofurans by acylation of 2-(2-hydroxy-5-nitrophenyl)-1-aryl-ethanones and subsequent treatment of the esters with combinations of bases and proton acids or Lewis acids. This process can be used for the production of Dronedarone. Furthermore, novel intermediates for the manufacture of Dronedarone are provided.
