  Flexible and Convergent Total Synthesis of Cyclotheonamide B

  摘要：

  A convergent approach using two key intermediates, segment A [a L-proline-L-alpha-hydroxy-beta-homoarginine-D-phenylalanine (Pro-hArg-D-Phe) tripeptide] and segment B [a vinylogous L-tyrosine-L-2,3-diaminopropanoic acid (vTyr-Dpr) dipeptide], was developed for the synthesis of cyclotheonamide B (Scheme 1). The starting compound for the preparation of the hArg moiety 7, the predominant part of segment A, was N-alpha-(benzyloxycarbonyl)-N-omega , N(omega)'bis(tert-butyloxycarbonyl)-l-arginine methyl ester (15, Scheme 2), which was converted into the aldehyde 16 and subsequently homologated using [tris(methylthio)methyl]lithium as a carboxylic acid anion equivalent. Coupling with properly protected Pro and D-Phe derivatives gave smoothly the desired Pro-hArg-D-Phe tripeptide derivative 24. The key feature of segment B, i.e., the L-tyrosine-derived alpha,beta-unsaturated gamma-amino acid 4, was prepared by a Wadsworth-Emmons olefination of the aldehyde 29 (Scheme 3) derived from N-(tert-butyloxycarbonyl), O-tert-butyl-L-tyrosine methyl ester (28). Selective N-(tert-butyloxycarbonyl) removal in the presence of the aryl tert-butyl ether present in the fully protected segment B, i.e., 32, was achieved by treatment with trimethylsilyl triflate/2,6-lutidine to give vTyr-Dpr dipeptide derivative 34 in quantitative yield. Coupling of the key intermediates 24 and 34 using 2-(1H-benzotriazol-l-yl)-1,1,3,3-tetramethyluronium tetrafluoroborate (TBTU) afforded the protected linear pentapeptide 35 in high yield (Scheme 4). Treatment of 35 with Pd(PPh3)(4)/morpholine resulted in simultaneous removal of the C-terminal allyl group and the N-terminal allyloxycarbonyl group to yield 36. Ring closure was effected under dilution conditions by treatment with TBTU/1-hydroxybenzotriazole/4-(dimethylamino and gave the protected cyclopentapeptide 37 in 61% yield. Oxidation of the hydroxyl group with Dess-Rlartin periodinane (24 h, 40 degrees C) in the presence of tert-butyl alcohol gave 38, which was then subjected to O,N-deprotection with trifluoroacetic acid/thioanisole. Subsequent HPLC purification afforded cyclotheonamide B in an overall yield of 1.8% in 17 steps.

  initiation. Herein we report the use of a chemoenzymatic strategy to complete the first total synthesis of GE81112 B1. By pairing iron and α-ketoglutarate dependent hydroxylases found in GE81112 biosynthesis with traditional synthetic methodology, we were able to access the natural product in 11 steps (longest linear sequence). Following this strategy, 10 GE81112 B1 analogues were synthesized, allowing for identification
