Regiodivergent and short total synthesis of calothrixins

Org. and Biomol. Chem. - 8 October, 2014 - 05:17

Org. Biomol. Chem., 2014, 12,8196-8203
DOI: 10.1039/C4OB01309C, PaperDipakranjan Mal, Joyeeta Roy, Kumar Biradha
The anionic annulation of MOM-protected furoindolone with 4-bromoquinoline followed by deprotection of the N-MOM group provides calothrixin B, whereas that with 3-bromoquinoline yields isocalothrixin B. The outcomes are explained by the divergence of the reaction mechanism from the commonly perceived 3,4-didehydroquinoline. A sequence of addition-cyclization-elimination is proposed to account for the formation of calothrixin from 4-bromoquinoline.
