A thirteen-step synthesis of the glyoxalase I inhibitor COTC (2-crotonyloxy-(4R,5R,6R)-4,5,6-trihydroxycyclohex-2-enone) from quinic acid is described.
Application of a tandem seleno-michael/aldol reaction in the total syntheses of (+)-Pericosine B, (+)-Pericosine C, (+)-COTC and 7-chloro-analogue of (+)-Gabosine C

, (2020/07/24)
Synthesis of (+)-Pericosine B, (+)-Pericosine C, (+)-COTC and a 7-chloro-analogue of (+)-Gabosine C was achieved via tandem seleno-Michael/aldol reactions as key steps. The carbasugar linear precursor was obtained from cheap and readily available D-ribose in 7 steps which included resolution of the D-ribopyranose and the D-ribofuranose forms. Further transformation of the cyclic product involving a regioselective Steglich esterification or methylation of the secondary hydroxyl group gave rise to protected (+)-COTC, (+)-Pericosine B and (+)-Pericosine C. Deprotection of benzyl ethers at ?78 °C gave the titled compounds in satisfactory yields.

The synthesis of 6-epi-COTC, a diastereoisomer of Streptomyces metabolite 2-crotonyloxymethyl-(4R,5R,6R)-4,5,6-trihydroxycyclohex-2-enone (COTC), is described. The anti-cancer activities of the novel analogue, in racemic and enantiomerically pure forms, a
High-pressure mediated asymmetric Diels-Alder reaction of chiral sulfinylacrylate derivatives and its application to chiral synthesis of (-)-COTC and (-)-gabosine C
Takahashi, Tamiko,Yamakoshi, Yoko,Okayama, Kazuya,Yamada, Junko,Ge, Wei-Ying,Koizumi, Toru
, p. 209 - 220 (2007/10/03)
The asymmetric Diels-Alder reactions of chiral sulfinylacrylate derivatives (1 and 2) with dienes (3-12) were examined under high-pressure (1.2 GPa) conditions. The endo cycloadduct (13e) obtained from sulfinyl acrylate (1) and 2-methoxyfuran (5) was converted to (-)-COTC (25) and (-)-gabosine C (26).

Tatsuta, Kuniaki,Yasuda, Shohei,Araki, Nobuyuki,Takahashi, Masaaki,Kamiya, Yuko
, p. 401 - 402 (2007/10/03)
A glyoxalase I inhibitor and (-)-KD16-U1 have been synthesized from D-ribonic acid γ-lactone through SnCl4-promoted cyclization of a phenylsulfonyl enol silyl ether and regioselective introduction of a hydroxymethyl group.
High pressure mediated asymmetric diels-alder reaction of chiral sulfinylacrylate derivatives with furan and 2-methoxyfuran
Yamakoshi, Yoko Nakajima,Ge, Wei-Ying,Sugita, Jun,Okayama, Kazuya,Takahashi, Tamiko,Koizumi, Toru
, p. 129 - 133 (2007/10/02)
Asymmetric Diels-Alder reaction of chiral sulfinylacrylate derivatives (1 and 2) with furan (3) and 2-methoxyfuran (4) proceeded under high pressure (1.2 GPa) conditions to give endo cycloadducts (6c-f). The absolute configuration of adduct (6) was confir
ENANTIOSELECTIVE TOTAL SYNTHESIS OF GLYOXALASE I INHIBITOR USING ASYMMETRIC DIELS-ALDER REACTION OF A NEW CHIRAL DIENOPHILE, (S)S-3-(3-TRIFLUOROMETHYLPYRID-2-YLSULFINYL)ACRYLATE.
Takayama, Hiromitsu,Hayashi, Kazuya,Koizumi, Toru
, p. 5509 - 5512 (2007/10/02)
Highly enantioselective total synthesis of Glyoxalase I inhibitor (1) was achieved utilizing the assymetric Diels-Alder reaction of a new chiral dienophile, (S)S-menthyl 3-(3-trifluoromethylpyrid-2-ylsulfinyl)acrylate (3) with 2-methoxyfuran.
