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 ...

Stereodefined enol derivatives of aldehydes are prepared from terminal alkynes. Specifically, terminal alkynes are known to undergo Cp2ZrCl2-catalyzed methylalumination. Here, we show that the ...
