Highly regio- and stereoselective synthesis of tricyclic frameworks using Baylis-Hillman derivatives

A simple and convenient synthetic route for the synthesis of tricyclic chromeno[4,3-b]pyrrolidine frameworks using Baylis-Hillman bromides involving in situ formation of an imine, decarboxylation and a [3+2] cycloaddition sequence is described.     

Applications of generalized inverses to interval linear programs in hilbert spaces

Let H₁ and H₂ be real Hilbert spaces. Suppose H₂ is partially ordered, a, b ? H₂ c ? H₁ and A :H₁ → H₂ is a continuous linear map. We consider the following interval linear program: Maximize subject to a ≤ Ax ≤ b.

Conditions under which explicit solutions to the above problem can be found are studied. The solutions are represented in terms of generalized inverses of A. Several examples are given to illustrate the main results.
