The first enantioselective total synthesis of penostatin E has been accomplished. Two highly efficient and diastereoselective reactions, a Hosomi-Sakurai allylation and an intramolecular Pauson-Khand reaction, were utilized for the construction of th

Oxidative radical cyclization of cyclic β-keto esters with alkenes is described. Substituted hydroxyhexahydrocyclopenta[b]furancarboxylates having substituents at the 2-position were produced in a diastereoselective manner when the reactions were ca

The reaction of propargylic carbonates with 4-hydroxy-2-pyrones in the presence of a palladium catalyst is described. By the choice of the reaction temperature, two types of the substituted furo[3,2-c]pyran-4-one derivatives were regioselectively syn

A palladium-catalyzed cyclization of 2-amidophenylmalonates with allylic bisacetates is described. Tetrahydroquinolines having a vinyl group at the 3- or 2-position were produced, in which the regioselectivity of the resulting products was altered de

This'll fix it: efficient fixation of atmospheric CO(2) has been achieved by the reaction of propargylic amines with a silver/DBU dual-catalyst system. Various oxazolidinones were synthesized in moderate to good yields by using substituted propargyli
