Perhaps you should try some spelling variations:
"synthesisd" » "synthesised", "synthesis", "synthesise"
"synthesedr" » "syntheseort", "synthese", "syntheses"
"synthesized" » "synthesisd", "synthesed"
"synthesize" » "synthesis", "synthese"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((("synthesized" OR "synthesisd") OR ("synthesedr" OR "synthesedr")) OR "synthesize").
• Removing quotes may allow a broader search: ((( synthesized or synthesisd ) or ( synthesedr or synthesedr )) or synthesize ).
• Adding a wildcard symbol may retrieve word variants: ((("synthesized" or "synthesisd") or ("synthesedr" or "synthesedr")) or "synthesize")*.
