  Enantioselective Syntheses of Syributin 1 and Novel C-Glycosidic Elicitors Syringolides 1 and 2

  摘要：

  Concise enantioselective syntheses of syributin 1 (3) and the novel nonproteinaceous C-glycosidic elicitors syringolides 1 and 2 (1 and 2, respectively), isolated from Pseudomonas syringae pv. tomato, are described. Syributin 1 was synthesized in one step by the Sharpless catalytic asymmetric dihydroxylation (AD reaction) of (1'E)-3-(3'-(octanoyloxy)-1'-propenyl)but-2-en-4-olide (13) in 72% yield with >98% ee. Furthermore, alkylation of (1'R,2'R)-3-[1'-(tert-butyldimethylsiloxy)-2,3'- (isopropylidenedioxy)propyl]but-2-en-4-olide (20), prepared from (1'E)-3-[3'-(tert-butyldimethylsiloxy)-1'-propenyl]but-2-en-4-olide (11) by the AD reaction, with hexanal or octanal by Jefford's procedure at the a position to the lactone carbonyl group gave adduct 21 or 22 in good yield. Oxidation of 21 or 2;2, followed by removal of the protecting groups, provided syringolide 1 or 2, respectively.

  Total Syntheses of Sphydrofuran, Secosyrins, and Syributins^,1

  摘要：

  Two groups of natural products, sphydrofuran (1) and its furan derivative (2) and secosyrins 1 and 2 (3a, 3b) and syributins 1 and 2 (4a, 4b), were synthesized from one precursor (6), which was realized starting from 3-tri-n-butylstannylfuran or 3-bromofuran.

  A synthesis of syributins 1 (5) and 2 (6) from D-glyceraldehyde acetonide (12)and furans (14) and (15) is described. Compounds (5) and (6) are cometabolitesof the novel non-proteinaceous C-glycosidic elicitormolecules the syringolides 1 (1) and 2 (2). Under a variety of acidicconditions, the intermediate butenolides (9) and (10) provided syributins 1(5) and 2 (6). Similar results have been reported

The two chiral centers of diisopropyl tartrate were incorporated into target natural products. Stereoselective construction of the spiro skeleton of secosyrins could be realized by taking advantage of an alkyne-cobalt complex.
