The most common chemical transformation of a carbon-carbon double bond is the addition reaction. A large number of reagents, both inorganic and organic, have been found to add to this ... The first two possibilities are examples of stereoselectivity, the first being termed syn-addition, and the second anti-addition.

A non-catalytic procedure for the syn-addition of hydrogen makes use of the unstable compound diimide, N2H2. This reagent must be freshly generated in the reaction system, usually by oxidation of hydrazine, and the strongly exothermic reaction is favored by the elimination of nitrogen gas (a very stable compound).

In Organic Chemistry , syn addition is the addition of two Substituent s to the same side (or face) of a Double Bond or Triple Bond , resulting in a decrease in Bond Order but an increase in number of substituents. ... Syn addition is in direct contrast to Anti Addition , which is addition of substituents to opposite sides...

When an alkene undergoes addition, two new s bonds form. If we think of an alkene as having two faces, then the two new s bonds can either both form on the same face, which we call syn addition, or they can be formed on different faces which we call anti addition.

Definition of Syn addition ... Syn addition is the addition of two substituents to the same side (or face) of a double bond or triple bond, resulting in a decrease in bond order but an increase in number of substituents. Generally the substrate will be an alkene or alkyne.

Everything I have read points to the idea that this should be an anti addition, but I don’t understand why the erythro diastereomer appears to have been formed by syn addition. I can not seem to work this problem out using my molecular models.
