Yeah, asymmetric synthesis of carbon-sulfur [7]helicene was great!  But with the iterative synthetic scheme, it seemed we could keep going and going…forever….ha ha ha,…on paper, of course.  It was kinda fun… plugging away the connection/annelation sequences…go on and on in many different ways.

Alright, we had the beautiful all-thiophene, or carbon-sulfur, [n]helicene structures drawn out.  The question was&#8230;how to make them?
Organic synthesis can be very arduous and challenging, especially for molecules with complex structures and those with such high degree of ring annelation, as well as with significant strain.

An unexpected discovery&#8230;that would be wonderful&#8230;  But sometimes one research project could lead to another unexpectedly&#8230;. This was how we started the carbon-sulfur helicene project.  So, when carrying out research projects, in addition to keeping our eyes wide open, we keep our mind open too.
