*This is the 5th post of the helicene series* After asymmetric synthesis of carbon-sulfur [11]helicene, we went back to the drawing board. plugging away at the connection/annelation sequencesthe next challenge was carbon-sulfur [15]helicene. Here is the retrosynthesis....

Alright, Fall semester is upon us once again, starting on Monday! Wow, so many happy smiling faces around here. Starting graduate school is surely exciting. Its a new beginningforget about the past record, it is all about the new ride..The road toward the finish...

It’s time for a post… and I am coming up short…again! Well, well, well, grad student members have been really into their research all summer long…. They have made good progress, so I suppose they have fun in the lab! Oh, well no help...

*This is the 4th post of the helicene series* Yeah, asymmetric synthesis of carbon-sulfur [7]helicene was great! But with the iterative synthetic scheme, it seemed we could keep going and goingforever.ha ha ha,on paper, of course. It was kinda fun plugging...
