In this manuscript, we are reporting an efficient protocol for the construction of highly functionalized N, O-heterocyclic derivatives such as 1,2,4-oxadiazine and 1,4,2-dioxazine-6-carboxylate derivatives via a 1,3-dipolar (3 + 3) cycloaddition betw

For the first time, we report the synthesis of 2-substituted N -alkoxy pyrrole 3-carboxylate and furan 3-carboxylate via Rh-catalyzed [3+2] cycloaddition between α-diazo oxime ether or α -diazo carbonyl compounds with vinyl equivalents in a one-pot

In this communication, for the first time, we are reporting α-diazo hydrazone synthesis from hydrazones derived from β-keto esters and 2,4-dinitro phenyl hydrazine via diazo transfer reaction. We also report an unexpected cyclization of the α-diaz

A Cu(OTf)2-catalyzed simple synthetic approach for highly substituted 1-alkoxy imidazole has been described. This protocol involves (3 + 2) cycloaddition of oximino carbenoids with organo nitriles. This method has wide substrate scope and tolerates a

For the first time, we have observed a combined effect of two bases NaOH/Et3N to promote the diazo transfer reaction of β-oximino esters. This unusual synergistic effect has been employed to obtain α-diazo oxime ethers directly from β-keto esters
