  Friedel-Crafts intramolecular cyclization in the presence of polyphosphoric acid of 2-substituted 5-phenylthiazole-4-carboxylic acids, which are obtained by alkaline hydrolysis of the corresponding esters, leads to indeno[2,1-d]thiazoles. According to the X-ray diffraction data, packing of their molecules in crystal is determined mainly by intermolecular pi-pi contacts, regardless of the substituent nature.

  A small library of compounds with an oxa(thia)zole scaffold and structural diversity in both positions 2 and 5 has been synthesized. Double acylation of a protected glycine affords intermediate alpha-amido-beta-ketoesters, which in turn can be dehydrated to afford 1,3-oxazoles or reacted with Lawesson's reagent to furnish 1,3-thiazoles. This procedure was designed with its adaptation to fluorous techniques in mind. Thus, when a protected glycine With a fluorous tag in the ester moiety IS used as a starting material, the synthesis can be easily completed Without column chromatography purification of intermediate compounds with good to excellent yields, thus affording a Suitable entry to the preparation of small libraries of these bioactive compounds. The prepared oxa(thia)zoles were assayed for their antibacterial activity, and several of them were active against Staphylococcus aureus.
