Enantiospecific total synthesis of macrolactone SCH 725674
Org Lett 2014 Aug 1;16(15):4001-3.PMID:25033232DOI:10.1021/ol5018678.
The enantiospecific total synthesis of 14-membered macrolactone SCH 725674 was accomplished from tartaric acid. Key reactions in the synthesis include the Ley's dithiaketalization of an alkynone derived from the bis-Weinreb amide of tartaric acid, Boord olefination, and ring-closing metathesis of an acrylate ester.
Regio- and Stereoselective Homologation of 1,2-Bis(Boronic Esters): Stereocontrolled Synthesis of 1,3-Diols and SCH 725674
Angew Chem Int Ed Engl 2016 Nov 14;55(47):14663-14667.PMID:27781356DOI:10.1002/anie.201608406.
1,2-Bis(boronic esters), derived from the enantioselective diboration of terminal alkenes, can be selectively homologated at the primary boronic ester by using enantioenriched primary/secondary lithiated carbamates or benzoates to give 1,3-bis(boronic esters), which can be subsequently oxidized to the corresponding secondary-secondary and secondary-tertiary 1,3-diols with full stereocontrol. The transformation was applied to a concise total synthesis of the 14-membered macrolactone, SCH 725674. The nine-step synthetic route also features a novel desymmetrizing enantioselective diboration of a divinyl carbinol derivative and high-yielding late-stage cross-metathesis and Yamaguchi macrolactonization reactions.
Structure elucidation of SCH 725674 from Aspergillus sp
J Antibiot (Tokyo) 2005 Aug;58(8):535-8.PMID:16266128DOI:10.1038/ja.2005.74.
A new macrolide Sch725674 (1) was isolated and identified from the culture of an Aspergillus sp. The structure elucidation of 1 was accomplished based on extensive NMR spectroscopic analyses. Compound 1 showed inhibitory activity against Saccharomyces cerevisiae (PM503) and Candida albicans (C43) with MICs of 8 and 32 microg/ml, respectively.
