Preparation of diverse BODIPY diesters

The synthesis and properties of a variety of substituted BODIPY diesters is presented. We find that certain substitution patterns afford appreciable yields of the target compounds and that electronic effects result in predicable differential fluorescent behavior. Challenges to further water solubilize these dyes and/or provide new points of attachment for biological tagging remain, these strategies are discussed.

Inter- and Intramolecular Cycloadditions of Nitroalkenes with Olefins. 2-Nitrostyrenes

Aromatic nitroalkenes 9 - 12 underwent Lewis acid catalyzed cycloadditions with various cyclic alkenes to afford high yields of nitronates 25 - 30 with exclusive anti selectivity.Hammett studies helped to further delineate the role of the Lewis acid.Reaction of nitroalkenes 8 and 10 with various cyclic dienes in the presence of a Lewis acid demonstrated the ability of nitroalkenes to behave as dienes in cycloadditions.The major products were the syn diastereomers which arise from an endo-folded transition structure.Finally, intramolecular cycloaddition of 36 - 39 allowed a correlation between the stereochemical course of the reaction and positions of sp2 centers in the tether to be addressed.
