Tubakialactone B

Description

8-Hydroxy-3,4-bis(hydroxymethyl)-6-methoxy-1H-isochromen-1-one belongs to the class of organic compounds known as isocoumarins and derivatives. These are polycyclic compounds containing an isochromane which bears a ketone at the carbon C1. Tubakialactone B is found in Tubakia sp. ECN-111. Tubakialactone B was first documented in 2017 (Nakashima, et al.). Based on a literature review very few articles have been published on 8-hydroxy-3,4-bis(hydroxymethyl)-6-methoxy-1H-isochromen-1-one.
