Undergraduate Project Report
The initial two subseries of leads have the general structure:
- TCMDC Aryl pyrrole core InChi Key: LNROIXNEIZSESG-UHFFFAOYSA-N
- Near-Neighbour core InChi Key: JZQOEGKHCXONAV-ZROIWOOFSA-N
A number of these compounds and intermediates are available for biological testing from Todd group by request.
The two known TCMDC series examples

The proposed resynthesis strategy for these two compounds:
The Near-Neighbour Sub-series
Known "Near Neighbours" contained in the Tres Cantos set
The original idea for investigation of the near-neighbour set came from Paul Willis and was posted on the synaptic leap.
