highly enantioselective organocatalytic version of the title reactionusing an in situ substrate generation/activation catalytic mode is described (see scheme). The reaction provides an efficient enantioselective construction of functionalized azaspirocyclic skeletons. The in situgeneration of the enolate provides a new way in which to use this important nucleophile in organic synthesis.

A first reported direct method for preparation of thymine thioglycoside analogs utilizing novel pyrimidine-2(1H)-thiones and α-bromoglucose or α-bromogalactose tetraacetate as starting components is described. The synthetic potential of the method is demonstrated. The evaluation of antiproliferative activity against HepG-2 cell lines (Liver carcinoma cell lines) shows that most of the compounds have

3-Amino-2-arylcarboxamide-thieno[2,3-b]pyridines are a known class of antiproliferative compounds with activity against the phospholipase C enzyme. To further investigate the structure activity relationships of these derivatives a series of analogues were prepared modifying key functional groups. It was determined that modification of the 3-amino and 2-aryl carboxamide functionalities resulted in complete elimination of activity, whilst modification at C-5 allowed compounds of greater activity to be prepared.
