cyclopentene to 1,5-pentadiol

(1/2) > >>

Darkstar:
Can you oxidize cyclopentene into 1,5-pentadiol in one stage?

movies:
Ozonolysis with a reductive work-up (NaBH4) should do the trick.

Darkstar:
Yes, apparently this is what they mean. A one stage process that consists of two parts :) I just thought maybe there's some sort of magic reagent I've never heard about, some selenium astatide or something...

movies:
I don't know much selenium chemistry, so there might be something.

Ozonolysis is always a two stage process.  I think that the NaBH4 step is essentially just tossing in some NaBH4 when the ozone addition is done, so it's virtually a one step conversion.  The ozonolysis to give the aldehydes would use a Me2S workup, so it's not like you would avoid a step otherwise.

huoshiyong:
with H2O2
