Kotani S, Kai K, Sugiura M, Nakajima M
Org Lett . 2017 Jun; 19(13):3672-3675. PMID: 28636385
An efficient method for accessing enantiomerically pure stereopentads via a catalytic asymmetric sequential aldol reaction has been developed for the first time. The enantioselective sequential aldol reaction produces a wide...

Kotani S, Kai K, Shimoda Y, Hu H, Gao S, Sugiura M, et al.
Chem Asian J . 2015 Nov; 11(3):376-9. PMID: 26610889
By using a phosphine oxide-catalyzed enantioselective double aldol reaction, we achieved the concise construction of C2 -symmetric 1,9-diarylnonanoids, enabling the synthesis of (-)-ericanone from p-hydroxybenzaldehyde in 6 steps with 65 ...

Ogawa Y, Sakurai N, Oikawa A, Kai K, Morishita Y, Mori K, et al.
Plant Cell Physiol . 2012 Mar; 53(5):943-52. PMID: 22437846
Suspension-cultured cell lines from plant species are useful for genetic engineering. However, maintenance of these lines is laborious, involves routine subculturing and hampers wider use of transgenic lines, especially when...

Saga H, Ogawa T, Kai K, Suzuki H, Ogata Y, Sakurai N, et al.
Mol Plant Microbe Interact . 2012 Feb; 25(5):684-96. PMID: 22295908
Camalexin is the major phytoalexin in Arabidopsis. An almost complete set of camalexin biosynthetic enzymes have been elucidated but only limited information is available regarding molecular mechanisms regulating camalexin biosynthesis....

Shimizu B, Kai K, Tamai M, Yamaguchi H, Mizutani M, Sakata K
Z Naturforsch C J Biosci . 2008 Dec; 63(9-10):687-90. PMID: 19040108
Oxidation of p-coumarate at the ortho-position is a key step to form umbelliferone. A tracer analysis using (18)O2 was performed in order to take information about the formation of umbelliferone...

Takahashi H, Kai K, Shinbo Y, Tanaka K, Ohta D, Oshima T, et al.
Anal Bioanal Chem . 2008 Jun; 391(8):2769-82. PMID: 18560811
Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR/MS) is the best MS technology for obtaining exact mass measurements owing to its great resolution and accuracy, and several outstanding FT-ICR/MS-based metabolomics...

Kai K, Mizutani M, Kawamura N, Yamamoto R, Tamai M, Yamaguchi H, et al.
Plant J . 2008 Jun; 55(6):989-99. PMID: 18547395
Coumarins are derived via the phenylpropanoid pathway in plants. The 2H-1-benzopyran-2-one core structure of coumarins is formed via the ortho-hydroxylation of cinnamates, trans/cis isomerization of the side chain, and lactonization....

Nakamura Y, Kimura A, Saga H, Oikawa A, Shinbo Y, Kai K, et al.
Planta . 2007 Aug; 227(1):57-66. PMID: 17701204
Differential metabolomics based on a non-targeted FT-ICR/MS analysis demonstrated metabolite accumulation patterns reflecting light/dark conditions in Arabidopsis T87 cell culture. First, FT-ICR/MS data sets were converted into metabolome information using...

Phytochemistry . 2006 Jan; 67(4):379-86. PMID: 16405932
The biosynthesis of coumarins in plants is not well understood, although these metabolic pathways are often found in the plant kingdom. We report here the occurrence of coumarins in Arabidopsis...
