What is it about?

a straightforward and rapid synthesis of(±)-tapentadol was achieved, with better diastereoselectivity,from totally different and commercially relevant raw materials.

Why is it important?

The synthetic operation from cheaply available tetrahydrothiopyr-an-4-one provided an added advantage of scale up at a lower cost than the acyclic strategy.

Perspectives

higher diastereoselectivity was obtained as compared with previous routes
