title = "Marine natural products-XVI. Polyhalogenated acyclic monoterpenes from the red alga plocamium of antarctica",
abstract = "Examination of the red alga Plocamium sp. collected near the Antarctic penninsula yielded three new acyclic halogenated monoterpenes (1-3). A structure revision is proposed for a compound previously reported to have structure 1. X-ray diffraction provided the structure of 1 including absolute stereochemistry. The structures of 2 and 3 followed from proton and 13C NMR spectral interpretation.",

note = "Funding Information: After reduction of the data, 679 of the 8$9 unique relkctions collected in an octant out to sin WA= 0.481 were accepted using the criteria of F 2 1.5 cp Attempts to solve the structure by Patterson methods were frustrated by a large number of overlapping peaks, hence, we resorted to a direct methods approach to locating the five halogen atoms.z The solutions and refinement then proceeded routinely to give the structure shown in the @ure. Large anomolous dispersion contributions from the halogen atoms resulted in a weighted residual of 9.9% for the correct con@uratio# as against 10.5% for the enantiomer. The final unweighted residual was 10.7%a nd X was l.85.24 Acknowkdgements-The algal sample was provided by Dr. T. E. DeLaca MSF-OPP-74121391.
