专利号:US-9512080-B2 优先权日:2012-07-10 标 题:Synthesis of acridinium compounds by N-alkylation of acridans 发明人:NATRAJAN ANAND; WEN DAVID 权利人:SIEMENS HEALTHCARE DIAGNOSTICS INC 摘要:A method is provided for N-alkylation of acridine compounds by reduction of acridines to corresponding acridans to improve the reactivity of the acridine nitrogen, and subsequent N-alkylation of the acridans in ionic liquid solvents to provide the corresponding acridinium compounds in high yield. This inventive process improves chemical conversion, and does not require the use of highly toxic alkylating agents, such as 1,3-propane sultone.

The aqueous solution is capable of sufficiently solubilize the activated Fmoc-α-amine protected amino acid or activated Fmoc-α-amine protected peptide fragment, and where the resin is capable of swelling in the presence of the aqueous solution above about 4 mLg-1. The invention also encompasses a method for regeneration of spent aqueous solution from the SPPS.

The catalyst contains an inorganic solid substance having a surface modified with an ionic substance containing a Group 15 element; or contains an ionic substance containing a Group 15 element, and an inorganic solid substance. The modifying group for surface modification of an inorganic solid substance is an ionic substance containing a Group 15 element. The ionic substance containing a Group 15 element is at least one substance selected from organic phosphonium salts, organic ammonium salts, organic arsonium salts and organic antimonium salts.
