摘要:
There is provided an improved method for the recovery of residual, unseparated β-ACF from reaction mixtures remaining from an initial synthesis of ACF, which is in particular usable on a large industrial scale, more particularly in the production of capecitabine.
摘要:
The present invention concerns a synthesis process comprising the following steps (i) reacting 3-ethyl-4-nitrobenzoic acid with thionyl chloride to produce a 3-ethyl-4-nitrobenzoic acid chloride or a 3-ethyl-4-nitrobenzoic acid anhydride from 3-ethyl-4-nitrobenzoic acid by means of water cleavage and (ii) Friedel-Crafts acylation by reacting the 3-ethyl-4-nitrobenzoic acid chloride or the 3-ethyl-4-nitrobenzoic acid anhydride with an optionally substituted aryl-H to form an optionally substituted (3-ethyl-4-nitrophenyl)-aryl-methanone. In addition the present invention concerns compounds containing (3-ethyl-4-nitrophenyl)-aryl-methanone, characterized in that the optionally substituted aryl is an optionally substituted condensed aromate.
摘要:
The present invention relates to a recycling process for the preparation of solid phase bonded 2-chlorotrityl chloride (2-CTC resin) useful for solid phase peptide synthesis, wherein active chloride CTC resin is regenerated by reacting the spent resin with a chlorinating agent in organic solvent.
