, p. 7499 - 7503 (2013/02/22)
Here we synthesized four novel indole conduritol derivatives 1-4 for the first time in the literature and probed their biological activities with the α and β-glucosidases. The compounds showed quite effective glucosidase inhibitory action. IC50
New Stereoselective Route to the Epoxyquinol Core of Manumycin-Type Natural Products. Synthesis of Enantiopure (+)-Bromoxone, (-)-LL-C10037α, and (+)-KT 8110

A practical route is decribed for the preparation of the C7N core of manumycin-type compounds. Starting from p-benzoquinone, optically pure compounds in both forms can be prepared via enzymatic resolution of a derived diacetoxy conduritol. A diepoxy aminoinositol is accessible which can function for formation of enantiopure epoxyquinones and quinols. Examples are given for acylation reactions of this amine with several acyl derivatives. With this approach (-)-LL-C10037α and quinones such as (+)-KT-8110 with 5A,6S-configuration can be synthesized through oxidation. In addition a short route to (+)-bromoxone is described. Most steps include simple epoxide formation and cleavage reactions which all can be carried out in a high stereoselective manner.
Enzyme-assisted total synthesis of the optical antipodes D-myo-inositol 3,4,5-trisphosphate and D-myo-inositol 1,5,6-trisphosphate: Aspects of their structure-activity relationship to biologically active inositol phosphates

, p. 1262 - 1273 (2007/10/03)
Unambiguous total syntheses of both optical antipodes of the enantiomeric pair D-myo-inositol 3,4,5-trisphosphate (Ins(3,4,5)P3) and D- myo-inositol 1,5,6-trisphosphate (Ins(1,5,6)P3) are described. The ring system characteristic of
A novel synthesis of Conduritol-C and Conduritol-E via p-benzoquinone
Secen,Maras,Sutbeyaz,Balci
, p. 2613 - 2619 (2007/10/02)
A new and sterospecific synthesis for Conduritol-C 8 and Conduritol-E 13a has been developed starting from p-benzoquinone 1. 1,4-oxygen functionalities were introduced in both synthesis by the reduction of dibromo p-benzoquinone 2 with NaBH4. 2
