The nomenclature of the bicyclic and spiro (mono) compounds are easy to understand. But when the number of spiro atoms or the number of rings exceeds 2, the nomenclature turns very complex. I cannot understand the method of numbering the carbons and the method of writing those bracketed numbers with dots and superscripts.
I have read the IUPAC Recommendations 2004, but the text given there is really hard to understand (for me only, I hope). I want to know the method of writing those numbers with the superscripts inside the bracket for spiro and cyclo compounds. Diagrams with arrows or a detailed text with one particular example, will be helpful.
