Bhosale, Shrikar M.,Gawade, Rupesh L.,Puranik, Vedavati G.,Kusurkar, Radhika S.

, p. 2894 - 2896 (2012)

An efficient synthesis of calothrixin B (2) is demonstrated starting from 9H-carbazol-4-ol, having two one-pot reaction sequences as key steps. As a novel observation, DMF-methanol was shown to be a hydride donor for reduction of aldehyde to alcohol. Unexpectedly, nucleophilic substitution of benzyloxy by methoxy group was observed.
