The first total synthesis and development of a variety of bioactive natural products have been accomplished by using carbohydrates as a chiral source by using the “Big Four” antibiotics and a side-chain of cephem antibiotics. Expand


Total Syntheses of Useful Bioactive Compounds
The first total syntheses of a variety of useful bioactive compounds have been accomplished by practically useful strategies. In addition practically useful intermediates have been developed,Expand
A New Method for the One-Step Synthesis of α,β-Unsaturated Carbonyl Systems from Saturated Alcohols and Carbonyl Compounds
Most of these protocols rely on highly toxic selenium reagents in oneor two-step procedures. 2 Another regularly employed tactic involves palladium-catalyzed oxidation of the enol-ethers derived fromExpand
UCE6, a new antitumor antibiotic with topoisomerase I-mediated DNA cleavage activity produced by actinomycetes: producing organism, fermentation, isolation and biological activity.
UCE6 exhibited growth inhibitory activity against HeLa S3, HCT116 and Lu-65 cells comparable to that of camptothecin and addition of silicone oil antifoam agent, KS69, to the fermentation enhanced the production of UCE6 by approximately 3 fold. Expand
Enantio- and diastereoselective aldol reactions of achiral ethyl and methyl ketones with aldehydes: the use of enol diisopinocampheylborinates
Abstract Enol diisopinocampheylborinates, derived from achiral ethyl and methyl ketones by enolisation in the presence of tertiary amine bases (iPr2NEt or Et3N), undergo enantio- andExpand
Diels–Alder reactions of 2-carbomethoxy-2-cyclohexen-1-one
Under stannic chloride catalysis, 2-carbomethoxy-2-cyclohexen-1-one (5) was found to undergo Diels–Alder reaction with a variety of dienes to give directly the cis-1-octalone system possessing aExpand
