The chemical composition of root and rhizosphere soil extracts of plant of Tagetes patula L. was investigated by GC-MS for the identification of allelochemicals. The dried and powdered root material was subjected to Soxhlet extraction using methanol. The rhizosphere soil around the plant was also extracted with methanol. GC-MS analysis of the roots and rhizosphere soil extracts led to identification of 25 and 27 compounds, respectively. The major compounds identified in methanol root extract were 5-hydroxymethylfurfural (21.81 %), butanoic acid, 2,2-dimethyl-3-oxo-methyl ester (11.71 %), 2,3-dihydro-3,5-dihydroxy-6-methyl-4H-pyran-4-one (12.68 %), 5-(4-acetoxy- 1-butynyl)-2,2?-bithienyl (8.50 %). However in rhizosphere soil extract dimethylsulfoxonium formylmethylide (6.32 %), 2-phenylthieno[2,3-b]thiophene (9.34 %), hexadecanoic acid (16.64 %), alpha-terthienyl (5.81 %), stigmasterol (5.32 %), gamma-sitosterol (5.71 %) were present as major compounds.

A series of novel 3-phenyl-3-[1-(cyclicalkyl)pyrrolidin-3-yl] glutarimide derivatives have been prepared, including their pharmaceutically acceptable salts. The cyclic moiety present in these compounds is derived from either benzene or a heteroaryl such as benzofuran or 2,3-dihydrobenzofuran, or it is derived from an aromatic heterocyclic such as pyridine, pyrazine or thiophene, and it is attached to the adjacent alkyl group of the molecule by means of one of the available ring carbon atoms situated in the aromatic ring of the aforementioned cyclic ring moiety. These particular compounds are useful in therapy as selective muscarinic receptor antagonists, which are selective for smooth muscle muscarinic sites over cardiac muscarinic sites and therefore, are of value in the treatment of diseases associated with altered motility and/or smooth muscle tone as found in the gut, trachea and bladder. Methods for preparing these compounds from known starting materials are provided.

The century-old fluoresceins and rhodamines persist as flexible scaffolds for fluorescent and fluorogenic compounds. Extensive exploration of these xanthene dyes has yielded general structure-activity relationships where the development of new probes is limited only by imagination and organic chemistry. In particular, replacement of the xanthene oxygen with silicon has resulted in new red-shifted Si-fluoresceins and Si-rhodamines, whose high brightness and photostability enable advanced imaging experiments. Nevertheless, efforts to tune the chemical and spectral properties of these dyes have been hindered by difficult synthetic routes. Here, we report a general strategy for the efficient preparation of Si-fluoresceins and Si-rhodamines from readily synthesized bis(2-bromophenyl)silane intermediates. These dibromides undergo metal/bromide exchange to give bis-aryllithium or bis(aryl Grignard) intermediates, which can then add to anhydride or ester electrophiles to afford a variety of Si-xanthenes. This strategy enabled efficient (3-5 step) syntheses of known and novel Si-fluoresceins, Si-rhodamines, and related dye structures. In particular, we discovered that previously inaccessible tetrafluorination of the bottom aryl ring of the Si-rhodamines resulted in dyes with improved visible absorbance in solution, and a convenient derivatization through fluoride-thiol substitution. This modular, divergent synthetic method will expand the palette of accessible xanthenoid dyes across the visible spectrum, thereby pushing further the frontiers of biological imaging.
