Abstract

Chemical investigation of the southern Australian marine alga Laurencia filiformis forma heteroclada resulted in the isolation of two new compounds, cycloisoallolaurinterol (16) and isoallolaurinterol (23), along with the previously reported sesquiterpenes filiformin (1), filiforminol (2), allolaurinterol (3) and bromolaurenisol (10). All structures were secured by detailed spectroscopic analysis since no previous 2D NMR studies had been described for compounds 1, 2 and 10. As a result of this study, the first single X-ray diffraction study for 1 was secured. The investigation of the chemical conversion of allolaurinterol (3) to filiformin (1) was monitored by on-flow HPLC-NMR, which also re..
