Make your rtf / doc document into docx and convert it with docx2tex .
You need the System.IO.Packaging.NET class to make it work, which does not present a problem if you use Windows, and in principle it is supported by Mono if you do not. If someone manages to do this with Mono, I would like to hear your impressions: this did not work a year ago, but their implementation of this class has improved since then.
I talk more about the utility in response to tex.stackexchange . Suffice it to say that I consider this to be the cleanest, most convenient option for Latex today.
