Derived isomorphism conjecture for finite-dimensional Lie algebras

Let g1\mathfrak{g}_1 and g2\mathfrak{g}_2 be finite-dimensional Lie algebras over C\mathbb{C}, and let Ug1\mathfrak{U}\mathfrak{g}_1 and Ug2\mathfrak{U}\mathfrak{g}_2 denote their enveloping algebras. Derived isomorphism conjecture. If the derived categories of bounded complexes of Ug1\mathfrak{U}\mathfrak{g}_1-modules and Ug2\mathfrak{U}\mathfrak{g}_2-modules are equivalent, then

g1g2.\mathfrak{g}_1\cong\mathfrak{g}_2.

The corresponding isomorphism problem for enveloping algebras is widely open in general, although it has a positive answer for semisimple and low-dimensional nilpotent Lie algebras. This derived version asks whether the bounded derived category determines a finite-dimensional complex Lie algebra.
