    5‐membered lactones 3p, 3q, 16 were obtained in moderate yields. The one‐pot synthesis of kawa lactones 3a, 3r, 3s and formal synthesis of dihydroxycystothiazole A and dihydroxycystothiazole C are presented. To elucidate the stereochemistry of (+)‐annularin G and (−)‐annularin H, the first asymmetric syntheses of these natural products were achieved.

  • A concise synthesis of (−)-indolmycin and (−)-5-methoxyindolmycin

    Concise syntheses of (-)-indolmycin 1 and (-)-5-methoxyindolmycin 3 were developed based on a palladium-catalyzed reaction of (2S,3R)-2-acetoxy-3-methyl-5-trimethylsilyl-4-pentynoate 6 with an o-iodoaniline derivative 10 or 11, followed by reaction with guanidine hydrochloride in the presence of base. An optically active internal alkyne (2S 3R)-6 was obtained by lipase-assisted enantioselective acetylation of (+/-)-(2,3)-syn-2-hydroxy-3-methyl-5-trimethylsily-4-pentynoate 4. (C) 2008 Elsevier Ltd.

    3S)-epoxy butanoate 5 gave the acetylenic ester 10, which was treated with MeOH in the presence of Bu3P to afford selectively (Z)-β-methoxy acrylate congener 11 in 86% yield. Treatment of (Z)-11 with 99.8% enrichment of CDCl3 followed by consecutive desilylation and oxidation afforded the left-half aldehyde (+)-2. The overall yield (10 steps from 5; 23%) of (+)-2 via the present route was improved in comparison
