cycloisomerization-initiated tandem reaction of Boc-protected indole tethered homopropargyl amides has been achieved. This method delivers a wide range of valuable bridged aza-[n.2.1] skeletons (n = 3–7) at roomtemperature with high diastereoselectivity and enantioselectivity by a chirality-transfer strategy. Moreover, the gold-catalyzed tandem reaction of homopropargyl alcohol is also achieved to produce

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 R

or R

on the A group is an aryl, heteroaryl or heterocycle (R

) are provided. The inhibitors described herein target factor D and inhibit or regulate the complement cascade at an early and essential point in the alternative complement pathway, and reduce factor D's ability to modulate the classical and lectin complement pathways. The inhibitors of factor D described herein are capable of reducing the excessive activation of complement, which has been linked to certain autoimmune, inflammatory, and neurodegenerative diseases, as well as ischemia-reperfusion injury and cancer.
