Although we learned that dissolving metal reductions can selectively reduce alkynesto alkenes with anti stereochemistry, we learned no such route for the anti hydrogenationof alkenes themselves. Devise two pathways by which you could combine other reactions toproduce the same product as the anti hydrogenation of a starting cis alkene.
