What? Do you have a high leg?
Transformers are made to do just that.
Figure your load and size accordingly then get a unit with a 208 volt primary and a 120/240 volt secondary.
If for example, the load figures out to need a 5KVA unit, the Square D model would be 5S7F. It has a 208 primary and a 120/240 secondary.
Other manufacturers will have the same unit, I just happened to have my Square D book handy.
Square D has then from 1KVA up to 167KVA.

Okay :blink: Tap two wires off your 3 phase 208 system and now you have a single phase circuit

Not really you could have a single phase 208 high leg.
But back to the question.
But I would go with a busk boost for the cost.
