  Total Synthesis of Dolatrienoic Acid:  A Subunit of Dolastatin 14

  摘要：

  The (7R,15R)- and (7S,15R)-diastereomers of dolatrienoic acid were synthesized using a convergent strategy. Fragment C5-C9 was obtained through enantiodifferentiation of racemic pentane-1,3,5-triol as the key step, fixing the chirality at C7 of fragments 4 and ent-4. The chirality at C15 of the fragment C10-C16 was introduced from L-glutamic acid. Coupling of these two fragments led to the aldehydes (7R,15R)- and (7S,15R)-2 which were homologated by Horner-Wadsworth-Emmons condensation to give (7R,15R)- and (7S,15R)-dolatrienoic acids.

• Total Synthesis of (−)‐5‐Deoxyenterocin and Attempted Late‐Stage Functionalization Reactions
  作者：Lilla Koser、Thorsten Bach

  DOI：10.1002/chem.202301996

  日期：2023.10.13

  The polyketide natural product (−)-5-deoxyenterocin (2) was stereoselectively synthesized from aldehyde 1, which was in turn obtained from pentane-1,3,5-triol and (−)-menthone. An attempted functionalization at position C5 remained futile, although several C−H activation methods could be successfully applied to (3aR)-(+)-sclareolide (3).

  聚酮化合物天然产物(-)-5-脱氧肠素( 2 )是由醛1立体选择性合成的，醛1又由戊烷-1,3,5-三醇和(-)-薄荷酮获得。尽管几种 C−H 激活方法可以成功应用于 (3a R )-(+)-香紫苏内酯 ( 3 )，但在 C5 位点的功能化尝试仍然徒劳。
• Synthesis and anti-tubercular activity of 2-nitroimidazooxazines with modification at the C-7 position as PA-824 analogs

  Tuberculosis (TB) is a major global health problem, and new drug targets and scaffolds need to be identified to combat the emergence of drug resistant TB.The nitroimidazooxazine PA-824 represents a new class of bio-reductive drug to treat TB. In this study we report a 2-nitroimidazooxazine derivative with modification at the C-7 position that exhibited better activity than PA-824 against Mycobacterium tuberculosis (Mtb) H37Rv strain in vitro. From 7a as a key intermediate, we functionalized with benzyl ether (8), phenyl ether (9), benzyl carbonate (10) and benzyl carbamate (11). Among the 23 compounds produced, 8a-R (MIC = 0.078 mu M) with trifluoromethoxy benzyl group was 5-fold more potent than PA-824 (MIC = 0.390 mu M) in the in vitro assays against the wild-type Mtb, and the phenyl ether compound 9g-R (MIC = 0.050 mu M) exhibited the most potent antimycobacterial activity.

• Stereoselective acetalization of 1,3-alkanediols by l-menthone: application to the resolution of racemic 1,3-alkanediols and to the determination of the absolute configuration of enantiomeric 1,3-alkanediols

  A general and reliable method for the resolution of racemic 1,3-alkanediols, which involves their conversion into diastereomeric spiroacetals derived from l-menthone, is described. Thus, the reaction of the bis-O-trimethylsilyl derivatives of racemic 1,3-alkanediols with l-menthone in the presence of a catalytic amount of trimethylsilyl trifluoromethanesulfonate affords the diastereomeric spiroacetals 3 and 4. The two can be readily separated by silica gel column chromatography. Hydrolysis of each diastereomer under acidic conditions liberates the corresponding enantiomerically pure diol. An empirically derived correlation of configuration and H-1 NMR chemical shifts for spiroacetals 3 and 4 has been developed which is rationalized based on long-range effects due to the magnetic anisotropy inherent to the menthane ring in a rigid spiroacetal conformation. The method described here should be widely applicable to the determination of the absolute configuration of various 1,3-alkanediols.
