摘要:The present invention relates to a process for the regioselective synthesis of compounds of the formula I, n nwherein R0; R1; R2; R3; R4; R5; A1; A2; A3; A4, Q and J have the meanings indicated in the claims. The present invention provides a direct copper catalyzed regioselective process to a wide variety of unsymmetrical, multifunctional N-substituted benzimidazoles or azabenzimidazoles of formula I starting from 2-halo-nitroarenes and N-substituted amides.

标 题 :Process for the preparation of glycerol-based crosslinked polymeric gels
发明人：PILLAI V N RAJASEKHARAN; DHANAPAL BOOPATHY
权利人:LIPAL BIOCHEMICALS; PILLAI V N RAJASEKHARAN; DHANAPAL BOOPATHY
摘要:The present invention relates to a process for the preparation of crosslinked polymeric gels for solid phase synthesis, the respective gels and their use. The gels are prepared by radical-induced copolymerisation of monomeric molecules and bifunctional crosslinking agents.
