"A Practical Access to [1-13C]1-Deoxy-D-xylulose and Its Derivatives"
Synlett, 2003(10), 1521-1523
A practical synthesis of [1-13C]1-deoxy-D-xylulose and its triacetate and 5-phosphate derivatives is described. The present scheme is developed based on the consideration of the cost efficiency of 13C

"Synthesis and Biological Evaluation of Water Soluble Taxoids Bearing Sugar Moieties"

Heterocycles, 2001, 54(2), 561-566
Synthesis and biological evaluation of a variety of water soluble taxoids with sugar moieties are described.

"An Efficient Conversion of Allyl Esters to Urethanes with Pd Catalyst"
Hiroshi Okumoto, Satoshi Nishihara, Sinya Yamamoto, Hirokazu Hino, Akihiro Nozawa, and Akira Suzuki
Synlett, 2000, 991-992
Reaction of allyl esters in proper alcohol with Pd catalyst in the presence of (PhO)2P(O)N3 and NaN3 at 80 ｡C directly gave urethanes through acyl azides and then isocyanates. The reaction in t-BuOH afforded amines protected with BOC, and free amines were obtained when water was present.

"Pd-Catalyzed Ring Opening of Cyclopropanols"
Hiroshi Okumoto, Takamitsu Jinnai, Hiroyuki Shimizu, Yoshinori Harada, Hideki Mishima, and Akira Suzuki
Synlett, 2000(5), 629-630
Treatment of substituted cyclopropanols with a Pd catalyst in MeCN at 50 ｡C gave enones in good yields.

"Pd(II)-Mediated Carbonylation of Propargylic Acetates Leading to g-Acetoxy-b-methoxy-a,b- unsaturated Esters"
Hiroshi Okumoto, Satoshi Nishihara, Hiroko Nakagawa, Akira Suzuki
Synlett, 2000(2) , 217-218.
Carbonylation of 1,1-disubstituted propargyl acetates in a cat.PdCl2/CuCl2/MeC(OMe)3/MeOH system under CO atmosphere (balloon) gave g-acetoxy-b-methoxy-a,b-unsaturated esters.

"Synthesis of New Baccatin III Derivatives through Transesterification of b-Keto Esters with a Protected 10-Deacetylbaccatin III"
Tadakatsu Mandai, Akiyoshi Kuroda, Hiroshi Okumoto, Katsuyoshi Nakanishi, Katsuhiko Mikuni, Ko-ji Hara, Ko-zo Hara
Tetrahedron Lett. 2000, 41(2), 239-242.
Synthesis of a new array of baccatin III derivatives bearing a b-keto ester appendage on C-13 is successfully achieved through transesterification of a wide range of b-keto esters with a protected baccatin III.

"A Semisynthesis of Paclitaxel via a 10-Deacetylbaccatin III Derivative Bearing a b-Keto Ester Appendage"
Tadakatsu Mandai, Akiyoshi Kuroda, Hiroshi Okumoto, Katsuyoshi Nakanishi, Katsuhiko Mikuni, Ko-ji Hara, and Ko-zo Hara
Tetrahedron Lett. 2000, 41(2), 243-246.
A semisynthesis of paclitaxel has successfully been accomplished starting from a newly developed baccatin III derivative bearing a b-keto ester appendage on C-13.

"A Practical Synthetic Method for a- and b-Glycosiloxyacetic Acids"
Tadakatsu Mandai, Hiroshi Okumoto, Tetsuta Oshitari, Katsuyoshi Nakanishi, Katsuhiko Mikuni, Ko-ji Hara, Ko-zo Hara
Heterocycles, 2000, 52(1), 129-132.
Dihydroxylation of allyl 2,3,4-tri-O-benzyl-6-O-tritylglycosides provides diols, the anomers of which can easily be separated by column chromatography in a practical scale. These anomers can be cleanly transformed into a- and b-glycosiloxyacetic acids, respectively, via oxidative cleavage of the diol followed by oxidation.
