  A stereochemically general synthesis of 2-deoxyhexoses via the asymmetric allylboration of 2,3-epoxy aldehydes

  摘要：

  A stereochemically general strategy for the synthesis of 2-deoxyhexoses is described. This new approach involves the asymmetric allylboration of epoxy aldehydes 12 and 13, prepared via the Sharpless asymmetric epoxidation reaction, as a means of establishing the stereochemistry of the sugar backbone. Thus, the matched double asymmetric allylborations of 12 and 13 using tartrate allylboronates (R,R)- and (S,S)-7, respectively, provide erythro epoxy alcohols 14 and 16 with excellent diastereoselectivity ( > 96:4) and enantioselectivity (greater-than-or-equal-to 96% ee). The mismatched double asymmetric reactions of 12 and 13 using (S,S)- and (R,R)-7, respectively, provided the diastereomeric threo epoxy alcohols 15 and 17 with lower (ca. 75:25) but still synthetically useful selectivity. The enantiomeric purity of the major diastereomer in each of these reactions was determined to be greater than that of the epoxy aldehyde precursors. Epoxy alcohols 14 and 16 were converted with excellent selectivity to the l-arabino (21) and l-xylo (26) tetrols via neighboring group assisted alpha-substitution reactions of the derived phenylurethane derivatives 18 and 23. Stereochemically complementary beta-opening reactions were accomplished by treating primary alcohols 38, 40, 42, and 44 [prepared from 14-17, respectively, by ethoxyethylation of C(4)-OH and removal of the C(7)-tert-butyldiphenylsilyl (TBDPS) ethers] with NaOH in aqueous t-BuOH at reflux. Acid-catalyzed hydrolysis of the C(4)-ethoxyethyl ethers then provided tetrols d-35 (from 14), d-21 (from 15), d-30 (from 16), and d-26 (from 17), each with excellent stereoselectivity. These tetrols were isolated and fully characterized as the tetraacetate derivatives 36, 22, 31, and 27, respectively. These beta-opening reactions proceed by way of an epoxide migration (29 to 33) that inverts the stereochemistry at C(6) and activates C(7) toward nucleophilic attack. It is necessary that the C(4) hydroxyl be protected in three of the four stereoisomeric series to minimize competitive epoxide migration pathways (cf. 29 to 32a). arabino tetrol 21 and lyxo tetrol 30 were converted to 2-deoxyglucose and 2-deoxygalactose, respectively, by a standard ozonolytic sequence and then to 2-deoxyglucitol pentaacetate (45) and 2-deoxygalactitol pentaacetate (46) via NaBH4 reduction of the 2-deoxy sugars, thereby confirming all stereochemical assignments. The epoxide beta-opening technology was also applied to epoxy benzyl ether 47 (prepared from 14) and epoxy BOM ether 49 (deriving from 16). These reactions provide tetrol derivatives 48 and 50, respectively, in which the C(4)- and C(5)-hydroxyl functionality are suitably differentiated for use in subsequent synthetic sequences.

  excellent nucleophiles in Pd-catalyzed allylic alkylation. The method allows for the stereoselective introduction of a wide range of side chains, including highly functionalized ones. Both diastereomers can be accessed through variation of the reaction conditions. Furthermore, the use of stannylated carbonates introduces vinylstannane motifs, which are eligible for subsequent C–C coupling reactions.

  Iridium-catalyzed aminations of allylic carbonates containing a variety of O-functional groups have been explored. High degrees of regio- as well as enantioselectivity were achieved with diacylamides under salt-free conditions and with arylamines. The results allowed the antiepilepsy drug (S)-vigabatrin to be prepared via a very short route.
