- Total syntheses of allocolchicines I (R = CO2Me, R1 = H; R = H, R1 = CO2Me), with the ester functionality in the C-ring at the C10 or C11 positions, is reported. An asym. synthesis of (7S)-allocolchicine I (R= H, R1 = C...
- Stereoselective synthesis of (+)-goniodiol, (+)-goniotriol, (-)-goniofupyrone, and (+)-altholactone using a catalytic asymmetric hetero-Diels-Alder/allylboration approach.

- The stereoselective total synthesis of several members of the styryllactone family was achieved efficiently from a common intermediate, prepd. by a catalytic asym. inverse-electron-demand hetero-Diels-Alder/allylboration...
- Synthesis of the L-acid (C1-C8) fragment of pamamycin-593 and de-N-methylpamamycin-579.
[作者:Miura, Ayako;Takigawa, Shin-ya;Furuya, Yukito;Yokoo, Yusuke;Kuwahara, Shigefumi;Kiyota, Hiromasa;,期刊:European Journal of Organic Chemistry, 页码:4955-4962 , 文章类型: 研究论文,,卷期:2008年-29]
- The L-acid (C1-C18) fragment I of pamamycin-593 and de-N-methylpamamycin-579, strong aerial mycelium-inducers of Streptomyces alboniger, was synthesized using a cis-selective iodoetherification and a nucleophilic addn. o...
- A stereocontrolled approach to ethers with two a stereocenters.

- The stereocontrolled synthesis of enantiomeric pairs of four ethers, in which the oxygen atom is flanked by two a stereocenters, has been achieved using a chiral base/arene chromium tricarbonyl activation approach.
- Stereoselective synthesis of bicyclo[4.2.1]nonanes - a temporary-bridge approach to cyclooctanoids.
