Good points. What I have is a new protecting group and there are details I want to include, for example I use a catalyst in the deprotecting-step, this is a vital part of the invention. What I want is to get as large number of readers as possible and they could be interested in the catalyst but not the protecting group. There are other details also thar are central to the work. Bur you are right, this will all be part of the abstract.
