The invention relates to a novel process, novel process steps and novel intermediates useful in the synthesis of pharmaceutically active compounds, in particular neutral endopeptidase (NEP) inhibitors.
A highlyenantioselective free carbene insertion into the N−H bond of amines has been achieved. Newly designed high-pKa Brønsted acid catalysts, chiral spiro phosphamides, were found to be key and promote the proton transfer of the ylide intermediates and control the enantioselectivity of the reaction. The reaction provides a new approach to amino acid derivatives.
已经实现了将高度对映选择性的游离卡宾插入到胺的 N-H 键中。发现新设计的高 p Ka Brønsted酸催化剂、手性螺磷酰胺是关键,可促进叶立德中间体的质子转移并控制反应的对映选择性。该反应为氨基酸衍生物的制备提供了一种新途径。
