The advent of organic synthesis and the understanding of the molecule as they occurred in
the nineteenth century and were refined in the twentieth century constitute two of the most …

The development of chiral ligands to fine-tune the stereocontrol has been recognized as a
crucial pillar of asymmetric catalysis. In contrast to the well-developed chiral pyridine …

The five-membered, nitrogen-containing pyrroline ring is a privileged structure. This ring is
present in many bioactive compounds from natural sources. Pyrrolines—the dihydro …

The first rhodium (II)‐catalyzed aza‐[4+ 3] cycloadditions of 1‐sulfonyl 1, 2, 3‐triazoles with
1, 3‐dienes have been developed, and enable the efficient synthesis of highly functionalized …

A stereoselective method for synthesis of trans-2, 3-disubstituted 2, 3-dihydropyrroles is
reported. N-Sulfonyl-1, 2, 3-triazoles prepared from terminal alkynes generate α-imino …

Rhodium-catalyzed asymmetric hydrogenation of alkyne-tethered cyclohexadienones
enables highly regio-and enantioselective reductive cyclization to afford cis …

The C (8)-selective nucleophilic cascade cyclization of quinoline N-oxide with easily derived
1, 6-enyne from phenol derivatives is demonstrated. A variety of quinoline N-oxide and …

Rapid reaction of NaBH4 with MeOH precludes its use as a solvent for large-scale ester
reductions. We have now learned that a catalytic amount of NaOMe (5 mol%) stabilizes …

Limonoid and limonoid-like natural products have demonstrated diverse bioactive properties
and attracted considerable synthetic efforts. They provide a good platform to examine the …

The construction of benzopyrone‐fused hydrobenzofuranones via DABCO‐catalyzed [3+ 2]
cyclization/deformylation cascade of p‐quinols with 3‐formylchromones is described. The …
