Dithionite Reduction Help!

elephant - 27-7-2011 at 00:47

I've been stuck for hours and hours, so any help would be great.

What would be the product when dithionite (or specifically, NaS2O4) reduces 3-phenacylideneoxindole?

I understand that 1 double bond would end up being hydrogenated, but I can't tell if it would be in one of the benzene rings, or on the alkene.

Please and thank you, oh so very much.
