Usha Ranjan Ghatak

Usha Ranjan Ghatak (1931–2005) was an Indian

U. R. Ghatak was born on 26 February 1931 at

Ghatak was married to Anindita and the couple lived in Kolkata. It was here he died, succumbing a massive heart attack, on 18 June 2005, at the age of 76, survived by his wife.[1]

Legacy

Ghatak's contributions were primarily on stereochemically controlled organic synthesis and he was known developing methodologies for the synthesis of polycarbocyclic diterpenoids and bridged-ring compounds.

Ghatak documented his researches by way of a book, A Century, 1876-1976[9] and a number of articles published in peer-reviewed journals;^{[10][note 1]} ResearchGate, an online article repository, has listed 148 of them.^[11] He mentored several doctoral scholars in their researches and his works have been cited by several authors.^{[note 2]} He was associated with journals such as Indian Journal of Chemistry (Sec B), Proceedings of Indian Academy of Sciences (Chem Sci) and Proceedings of the Indian National Science Academy as a member of their editorial boards and served as a member of the Indian National Science Academy Council from 1994 to 1996.^[4]
