Hello together,
may you can help me to find a IUPAC name for this guy here?
It's importent for my thesis.
Thank you very much
The Start should may be 1-phenyl-1,2,3,3a-tetrahydrobenzo[d]pyrrolo[2,1-b]oxazole for the first three rings. But how to connect the next ring in that name?
Or is the benzoxazole-ring should be prior instead of the most prior single ring - oxazole?

PS: stereochemistry does not matter, its racemic
Relative stereochemistry does matter, even if it is racemic. I think* this compound can exist as 10 possible stereoisomers - 4 enantiomeric pairs and two meso compounds.
Saying it is racemic is not enough, you have to indicate which pair of enantiomers it is.
*A cursory "back of the envelope" analysis, the numbers here may not be correct but my point that stereochemistry matters is still relevant.

1H-NMR says its one diastereomer. X-ray diffraction gave me a C2-symmetrical structure.
I will just call it Hexacyclus.
But thanks for thinking of an solution.

Well if you're going to disregard all conventions of chemical nomenclature, at least call it something amusing. How about Jesus?

I am still about a conventional nomenclature. First question ist still: What is the parent ring? oxazole or benzoxazole. And how to deal with the situation that there two equals of them.

I am rather more blasé about nomenclature. In a journal, it could have a name like Structure 28.
With the structure, you could use any number of ways of naming it. If you want to use a semi-systematic name (1-chloro-2-methyl-chickenwire), then the central joined heterocycles are probably named something like 2,2'-bibenzoxazoline. I'm not advocating this name, simply naming the parent ring(s).
