default-information originate trigger

Has anyone ever be able to trigger default-information originate if the current routing process does not have a default route. I have been able to get something similar to work using a route-map and triggering on a certain address. 

Basically, I want to inject a default route into and ospf process if one doesn't existence in the routing table 

R1-R2-R3 and let say R1 has a default-information originate always, I want R2 to default-information originate always only if R1 is unreachable

Hello,

I am trying to tweak the scenario below so that the access list or the prefix list denies the default route. Not sure if it works, though...
