Etymologically, the entry records: For Hermann Emil Fischer, German chemist. Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is Fischer indole synthesis, spelled F-I-S-C-H-E-R- -I-N-D-O-L-E- -S-Y-N-T-H-E-S-I-S, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
