[reaction: see text] A novel one-pot synthesis of indole systems via tandem hydroformylation/Fischer indole synthesis starting from olefins and arylhydrazines is described. This tandem procedure leads directly to 3-substituted indoles if unsubstituted phenylhydrazine is used and to 3,5- respectively 3,7-disubstituted indoles if para- or ortho-substituted arylhydrazines are used.

An efficient approach for the generation of benzo[b]naphtho[2,3-d]oxocin-6-ones through a palladium-catalyzed tandem reaction of 2-alkynylphenol with 2-(2-bromobenzylidene)cyclobutanone is described. This tandem process afforded the fused polycycles easily, with the formation of three bonds with high efficiency, starting from easily available materials. Good functional group tolerance as well a...

this study was designed to find out the impact of the variable number of tandem repeats (vntr) of the tumor necrosis factor receptor 2 (tnfrsf1b) on pulmonary tuberculosis (ptb) risk in an iranian population. this case-control study was done on 159 ptb patients and 158 healthy subjects. bi-allelic tnfrsf1b vntr was genotyped by polymerase chain reaction. logistic regression analysis revealed no...

for the first time lactic acid was applied as an efficient and green catalyst for the one-pot three-component synthesis of amidoalkyl naphthols via the condensation between arylaldehydes, 2-naphthol and amides or urea under thermal solvent-free conditions in good to excellent yields. we have demonestrated a mild and efficient eco-friendly tandem synthesis of amidoalkyl naphthols using lactic ac...

An efficient route to 5H-benzo[d]imidazo[5,1-b][1,3]thiazines has been developed using the copper(i)-catalyzed tandem reaction of o-alkynylphenyl isothiocyanates with isocyanides in THF with Cs2CO3 as base. The present tandem process allows the assembly of a variety of 5H-benzo[d]imidazo[5,1-b][1,3]thiazines in good to excellent yields.

A series of functionalized 4H-chromenes have been constructed by using a novel FeCl(3)-catalyzed benzylation-cyclization tandem reaction.

We demonstrated tandem ring-opening/ring-closing metathesis (RO/RCM) polymerization of monomers containing two cyclopentene moieties and postmodification via insertion polymerization. In this system, well-defined polymers were efficiently formed by tandem cascade RO/RCM reaction pathway. Furthermore, these polymers could be transformed to new A,B-alternating copolymers via a sequential cross me...
