Monosubstituted pyrrolizin-3-ones 1 with substituents at the 1-, 5-,
6- or 7-positions are prepared in excellent yield by flash vacuum
pyrolysis (FVP) of appropriate Meldrumâs acid derivatives 2. The
mechanism involves formation of the pyrrol-2-ylmethylideneketene 29,
which can also be generated thermally from 3-(pyrrol-2-yl)propenoate
esters (e.g. 30). This alternative route has been used to make
a range of 2-substituted pyrrolizin-3-ones, again in excellent yield.
The 3-oxo-3H-pyrrolizine-2-carboxylic acid 42 could not be made
in this way owing to facile decarboxylation to pyrrolizinone 1, and
extension to the formation of the azaazulenone 48 was again
unsuccessful.
The invention is directed to substituted thieno[2,3-b]pyrrolidin-5-ones. The compounds are useful as inhibitors of cellular production of tumor necrosis factor (TNF-&agr;) and as antiproliferative agents. These compounds are useful in the treatment or control of neuro-degenerative diseases, cardiovascular diseases, cancer or inflammatory diseases.
and formylation. Condensation of these aldehydes with activated pyrroles in the presence of phosphoryl chloride provides analogues of prodigiosin, which differ from the natural products in the nature of the heteroatoms. gas-phase reactions - heterocycles - pyrroles - prodigiosins
Disclosed are novel 4,5-azolo-oxindoles having the formula ##STR1## These compounds inhibit cyclin-dependent kinases (CDKs), in particular CDK2. Thus, these compounds and their pharmaceutically acceptable salts, and prodrugs of said compounds, are anti-proliferative agents useful in the treatment or control of cell proliferative disorders, in particular cancer. Also disclosed are pharmaceutical compositions containing these compounds, and methods for the treatment and/or prevention of cancer, particularly in the treatment or control of solid tumors using these compounds, as well as intermediates useful in the preparation of compounds of formula I.
