For selection of lys2 auxotrophs you can use aminoadipic acid.  The 
method is described in Methods in Enzymology 194 (I think) under 
mutant selection.  This is the Genetic and Molecular Biology of 
Yeast volume.  I think this is the correct title.

Sorry for the vagueness of my reply, but I don't have my resourses
available at the moment.  I hop this information is of use.
