nucleophilic addition/annulation reaction of ortho-alkynylbenzaldehydes in the presence of methanol. The reactions of aryl-, trimethylsilyl- and diethoxymethyl-substituted alkynylbenzaldehydes occurred with complete regioselectivity in good to excellent yields undermicrowaveirradiation. The reactions of alkyl-substituted alkynylbenzaldehydes took place with good yields and high regioselectivity only when

5-diketopiperazine (DKP) derivatives, is compatible with both aromatic and aliphatic aldehyde components, and can intercept either intra- or intermolecular cycloaddition manifolds. Priming of one aza-bridging function in the intermediate [2.2.2]-DKP scaffold permits cycloreversion (microwave heating) and selective extrusion of cyanate derivatives leading to the formation of 2-pyridone structures. Progress
A variety of substituted dihydroisobenzofurans can be easily synthesized in high yields by a one-pot three-component approach starting from o-bromoarylaldehydes, methanol, and terminal alkynes. The reaction occurs through an unprecedented cooperative palladium/base promoted coupling/addition/cyclization sequence. (C) 2010 Elsevier Ltd. All rights reserved.

The present invention provides compounds and methods for the treatment of LFA-1 mediated diseases. In particular, LFA-1 antagonists are described herein and these antagonists are used in the treatment of LFA-1 mediated diseases. One aspect of the invention provides for diagnosis of an LFA-1 mediated disease and administration of a LFA-1 antagonist, after the patient is diagnosed with a LFA-1 mediated disease. In some embodiments, the LFA-1 mediated diseases treated are dry eye disorders. Also provided herein are methods for identifying compounds which are LFA-1 antagonists.
