Natural cembranoids studies

PROGRESS OF STUDIES ON THE NATURAL CEMBRANOIDS FROM THE SOFT CORAL SPECIES OF SARCOPHYTON GENUS... [Pg.257]

In the synthetic studies on cembranoid natural products by Marshall et al. [155], an alcohol-halide coupUng was used to construct the macrocycles. As shown in Scheme 87, the linear precursor 259 was cyclized to 260 in 71 /o yield by addition of 1 equiv of EtMgBr to a solution of the chloro alcohol 259 in HMPA-THF and stirring at reflux for 4 h. There are also other examples of this macrocyclization method [156]. [Pg.163]
