The first total synthesis of (±)-pallescensin B
Pallescensins are a group of furanosesquiterpenoids isolated from the marine sponge Disidea pallescens by Cimino et al.1 The common feature of these terpenoids is that they all contain a furan moiety; however they have carbon skeletons of varying complexity. Among the pallescensins, pallescensin B 1 presents the most complex architecture, with a unique bicyclo[4.2.2]decane system fused to a fur...
متن کاملThe first asymmetric total synthesis of (+)-coriandrone A and B.
The first enantioselective total synthesis of (+)-coriandrone A and B, two bioactive natural products, has been achieved in 10 steps and 11 steps starting from commercially available methyl 2-hydroxy-4-methoxybenzoate. Key reactions include a Claison rearrangement, a Shi-type epoxidation-cyclization sequence and ortho-metallation of t-butylbenzamides with (S)-(-)-propylene oxide reaction.

Total Synthesis of Septocylindrin B and C-Terminus Modified Analogues
The total synthesis is reported of the peptaibol Septocylindrin B which is related to the well documented channel forming peptaibol antibiotic Alamethicin. Several analogues were synthesized with a modified C-terminus, to investigate the SAR of the terminal residue Phaol. All these peptides were tested for their membrane perturbation properties by fluorescent dye leakage assay and for their ant...
