crawlingmcedge, OP said
I have recently synthesized a common drug used every day in hospitals around the world. It took 10 steps, but I think I can apply a new reaction and cut it down to 6 steps.
So, by this standard he may have quite a high impact journal he should target.
OP, I should caution you that you shouldn't get delusions of grandeur until you have actually applied this new reaction and cut out the steps. Organic synthesis is not known for being highly predicable.
And while publishing is great, this could be worth a lot of money to a pharmaceutical company, so you may want to investigate selling your idea to the highest bidder. Be very careful with your IP, they are sharks.
