Synthesis of Ethylenic and Acetylenic Triorganotins with Bulky Organic Ligands
The syntheses of trineophyl(1a) and tri-(-)-menthylstannyl phenylacetylene (1b) as well as that of (E)-1-trineophylestannyl-2-phenylethene (2) and (E)-1-trineophylstannyl1,2-diphenylethene (3) are described. The hydrostannation of 1a with an excess of trimethyltin hydride led to 1,1,1-tris(trimethyltin)-2-phenylethane (4) and/or 1,1-bis(trimethyltin)2-phenylethene (5) depending on the reaction ...
متن کاملSynthesis, antimalarial and antitubercular activity of acetylenic chalcones.
A series of acetylenic chalcones were evaluated for antimalarial and antitubercular activity. The antimalarial data for this series suggests that growth inhibition of the W2 strain of Plasmodium falciparum can be imparted by the introduction of a methoxy group ortho to the acetylenic group. Most compounds were more active against non-replicating than replicating cultures of Mycobacterium tuberc...
متن کاملA [3 + 2]-annulation approach to tetrasubstituted furans from MBH-carbonates of acetylenic aldehydes via sequential substitution/cycloisomerization.
A novel metal-free approach to construct the tetrasubstituted furans from Morita-Baylis-Hillman (MBH)-carbonates of acetylenic aldehydes has been developed. This strategy involves the cascade nucleophilic substitution/5-exo-dig-cycloisomerization of MBH-carbonates with 1,3-dicarbonyl compounds to give uniquely substituted 2-furan-3-yl acrylates. Additionally, the obtained furan adducts open a n...
متن کاملLITHIUM PERCHLORATE MEDIATED AMINATION REACTION OF ALDEHYDES: A NOVEL METHOD FOR SYNTHESIS OF N, N-DIALKYL-p-SILYLATED AMINES*
P-Silylated N,N-dialkyl amines (5) were easily synthesized in good to excellent yield from aldehydes (1), trimethylsilyldialkylamines (2), and trimethylsilylmethylmagnesium chloride (4) in the presence of 5 M lithium perchlorate solution in diethyl ether. The reaction Of (2) with aldehyde proceeded smoothly in the LiCI0 , to give the imimum salt (3). Addition of trimethylsilylmethylrnagnes...
متن کاملStereoselective synthesis of vinylsilanes by a gold(I)-catalyzed acetylenic sila-cope rearrangement.
Cationic tri-tert-butylphosphinegold(I) serves as a catalyst in the sila-Cope rearrangement of acetylenic allylsilanes. When phenol is employed as a nucleophile, the reaction allows for the stereoselective synthesis of vinylsilanes. Alternatively, use of methanol as a nucleophile leads to cyclic vinylsilanes, which can be viewed as latent vinylsilanes that are revealed on treatment with a mild ...
