We present the first total synthesis of eight ent-pimaranes via a short and enantioselective route (11–16 steps). Key features of the divergent synthesis are a Sharpless asymmetric dihydroxylation, a ...

Until the early 1970s, nearly all filter synthesis techniques were based on the extraction of electrical elements (lumped capacitors and inductors, transmission line lengths) from the polynomials that ...
