The stereochemistry of the biohydroxylation was determined on the basis of a NOESY-experiment and GIAO calculations at the B3LYP/cc-pVDZ level. A strong gamma-effect was observed at C15 of the agarofuran ring which was correctly predicted by the GIAO-B3LYP calculations}, language = {en} } @article{AlarconAlderetePeteretal.1998, author = {Alarcon, Julio and Alderete, Joel B. and Peter, Martin G. and Becerra, Juan J. and Silva, M.}, title = {Study on synthesis of 3 alpha,4 alpha-dihydroxy-dihydro-beta-agarofuran}, year = {1998}, language = {en} }
