烯丙胺与乙炔二甲酸二甲酯的反应在质子酸催化下得到 15,这是迈克尔加成和氮杂-克莱森重排的产物。该序列涉及4c或19-21的迈克尔加成以生成中间体N-烯基铵盐14,其经历电荷加速重排为15。甲苯磺酸是用于麦克尔加成步骤的有用催化剂。苯甲酸无效,因为中间体 14 被苯甲酸反离子竞争性脱烷基。在一种情况下,中间体 N-链烯基铵离子 18 已被 1 H NMR 光谱检测到,并已观察到在 -20 o C 下发生氮杂-克莱森重排

Adding an aryne to a tertiary allylamine affords o‐allylaniline products of an aza‐Claisenrearrangement. The aryne simultaneously provides the π component for the rearrangement and the quaternization event that lowers the activation energy for the sigmatropic shift. The reaction was applied to the synthesis of medium‐ring benzannulated amines (see scheme).

Compounds, methods of use, and processes for making inhibitors of complement Factor D comprising Formula (I), or a pharmaceutically acceptable salt or composition thereof wherein R¹² or R¹³ on the A group is a phosphonate substituent (R³²) are provided. The inhibitors described herein target Factor D and inhibit or regulate the complement cascade. The inhibitors of Factor D described herein reduces the excessive activation of complement.
