Green Chemistry Approaches to the Synthesis of 5-Alkoxycarbonyl-4-aryl-3,4- dihydropyrimidin-2(1H)-ones by a Three-Component Coupling of One-Pot Condensation Reaction: Comparison of Ethanol, Water, and Solvent-free Conditions
TL;DR: This method provides an efficient and much improved modification of original Biginelli reaction reported in 1893, in terms of high yields, short reaction times, and simple work-up procedure, and it has the ability to tolerate a wide variety of substitutions in all three components, which is lacking in existing procedures.
Journal ArticleDOI
A highly diastereoselective, practical synthesis of allyl, propargyl 2,3,4,6-tetra-O-acetyl-β-d-gluco, β-d-galactopyranosides and allyl, propargyl heptaacetyl-β-d-lactosides
TL;DR: In this paper, commercially available β-d -glucopyranose pentaacetate, β- d -galactopyrnose pentaaacetate and β - d -lactose heptaacetate were reacted with propargyl alcohol in the presence of BF 3 -Et 2 O catalyst to obtain in high yield and selectivity, the corresponding propargy derivatives, respectively.
Journal ArticleDOI

Hari Babu Mereyala,Maju Joe +1 more
TL;DR: Extensive examination of the activity of more than 50 cytotoxic styryl lactones isolated/synthesized belonging to the genus goniothalamus representing future generation of antitumor drugs is described for the first time at the molecular level.
Journal ArticleDOI
TMSCl‐mediated one‐pot, three‐component synthesis of 2H‐indazolo[2,1‐b]phthalazine‐triones
TL;DR: In this paper, a simple, efficient, and cost-effective method for the synthesis of 2H-indazolo[2,1-b]phthalazine-1,6,11(13H)-trione derivatives by a one-pot, three-component condensation reaction of phthalazide, dimedone, or 1,3-cyclohexanedione and aromatic aldehydes under CH3CN/DMF (8:2) media at 80°C for 30-60 min in the presence of trimethylsilyl chloride (

Stereoselective synthesis of α-linked saccharides by use of per O-benzylated 2-pyridyl 1-thio hexopyranosides as glycosyl donors and methyl iodide as an activator
TL;DR: In this paper, a new, practical, stereoselective glycosidation methodology is described where per O -benzylated 2-pyridyl 1-thio-α/β-hexopyranosyl donors of D -gluco-( 1), D -galacto-( 2 ), D -manno-( 3 ) and L -rhamno-( 4 ) configurations have been efficiently coupled with diverse sugar alcohols on activation by methyl iodide to obtain the α-linked disaccharides.
