  High-Yielding Diastereoselective syn -Dihydroxylation of Protected HBO: An Access to D-(+)-Ribono-1,4-lactone and 5-O -Protected Analogues

  摘要：

  A diastereoselective chemoenzymatic synthetic pathway to D‐(+)‐ribono‐1,4‐lactone, a versatile chiral sugar derivative widely used for the synthesis of various natural products, has been designed from cellulose‐based levoglucosenone (LGO). This route involves a sustainable Baeyer‐Villiger oxidation of LGO to produce enantiopure (S)‐γ‐hydroxymethyl‐α,β‐butenolide (HBO) that is further functionalized with various protecting groups to provide 5‐O‐protected γ‐hydroxymethyl‐α,β‐butenolides. The latter then undergo a diastereoselective and high‐yielding syn‐dihydroxylation of the α,β‐unsaturated lactone moiety followed by a deprotection step to give D‐(+)‐ribono‐1,4‐lactone. Through this 4‐step synthetic route from LGO, D‐(+)‐ribono‐1,4‐lactone is obtained with d.r. varying from 82:18 to 97:3 and in overall yields between 32 and 41 % depending on the protecting group used. Moreover, valuable synthetic intermediates 5‐O‐tert‐butyldimethylsilyl‐, 5‐O‐tert‐butyldiphenylsilyl‐ as well as 5‐O‐benzyl‐ribono‐1,4‐lactones are obtained in 3 steps from LGO in 58, 61 and 40 %, respectively.

  A short synthesis of the title compound, 16, from d-ribonolactone is described. Two alternative approaches differing in the timing of the CC double bond creation are used to prepare some chiral derivatives of 16. (−)-Ranunculin, a glycoside present in Ranunculaceae, has been synthesized for the first time.

  Nitrogen functions have been introduced stereoselectively at the C-2 position in D-ribonolactone derivatives in order to prepare the title unnatural amino acids. The synthetic strategies lie in the inversion of configuration in SN2-type substitution reactions and stereospecific hydrogenation of conveniently substituted butenolides. The -isomer is the key precursor in the synthesis of the antibiotic

  An efficient route towards biologically relevant pentose derivatives is described. The de novo synthetic strategy features an enantioselective alpha-oxidation reaction enabled by a chiral amine in conjunction with copper(II) catalysis. A subsequent Mukaiyama aldol coupling allows for the incorporation of a wide array of modular two-carbon fragments. Lactone intermediates accessed via this route provide a useful platform for elaboration, as demonstrated by the preparation of a variety of C-nucleosides and fluorinated pentoses. Finally, this work has facilitated expedient syntheses of pharmaceutically active compounds currently in clinical use.
