The total syntheses of (−)-magellanine, (+)-magellaninone, and (+)-paniculatine were
completed from diethyl l-tartrate via the common intermediate in a stereoselective manner. The …

Many anti-human immunodeficiency virus 1 nucleoside reverse-transcriptase inhibitors have
low central nervous system (CNS) distribution due in part to active efflux transport at the …

Purpose The purpose of this study was to clarify the localization and function of the ATP-binding
cassette transporter G2 (ABCG2; BCRP/MXR/ABCP) in retinal capillary endothelial cells…

The formal synthesis of (+)-nakadomarin A was completed. The significant points of this
synthesis are the highly stereoselective formation of the diazatricyclo[6.4.0.0 ]dodecane skeleton …

The first total synthesis of (+)-achalensolide was achieved from a commercially available d-(−)-isoascorbic
acid. The known epoxide, derived from d-(−)-isoascorbic acid, was converted …

Upon treatment with 30 mol % of Co 2 (CO) 8 and 30 mol % of TMTU in toluene at 70 C,
benzene-bridged alkynecarbodiimides efficiently underwent a ring-closing reaction to give the …

The first total syntheses of two tricyclic sesquiterpenes 1 and 2, isolated from Jatropha
neopauciflora , were completed from dimethyl d-tartrate in a stereoselective manner. The crucial …

The first and stereoselective total syntheses of (−)-ichthyothereol (1) and its acetate ((+)-2)
were achieved by incorporation of the two chiral centers of diethyl l-tartrate. The starting …

A highly stereoselective method for constructing a (2E)-methoxymethylidene-1,6-dioxaspiro[4.5]decane
skeleton has been developed on the basis of the palladium(II)-catalyzed ring-…

Treatment of the 3,4-dioxygenated-9-hydroxy-1-nonyn-5-one derivative, derived from
diethyl l-tartrate, with a palladium catalyst in methanol under a CO atmosphere effected an …
