Efficient assembly of the phomactin core via two different macrocyclization protocols.
Houghton,Choi,Rawal
, p. 3615 - 3617 (2001)
[reaction--see text] The core structure of phomactins C and D was assembled by an efficient strategy starting from 3,4-dimethylcyclohexen-2-one. Key reactions include (1) a high yielding and highly diastereoselective Michael addition of a mixed cuprate, (
An efficient and stereoselective synthesis of the monomeric counterpart of marinomycin A
Amans, Dominique,Bellosta, Veronique,Cossy, Janine
, p. 1453 - 1456 (2007)
Equation presented The monomeric counterpart of marinomycin A, an antitumor-antibiotic marine natural product, was synthesized efficiently in 11 steps from the commercially available ethyl (R)-(-)-3-hydroxybutyrate. The strategy was highlighted by a cruci

New sesquiterpene backbones are accessible after biotransformation of presilphiperfolan-8β-ol synthase (BcBOT2), a fungal sesquiterpene synthase, with non-natural farnesyldiphosphates in which methyl groups are shifted by one position toward the diphosphate terminus. One of the macrocycles formed, a new germacrene A derivative, undergoes a Cope rearrangement to iso-β-elemene. Three of the new terpenoids show olfactoric properties that range from an intense peppery note to a citrus, ozone-like, and fruity scent.
Dialkoxycarbenes in (4 + 1) Cycloadditions: Application to the Synthesis of Carotol

Dialkoxycarbenes are more reactive than NHCs and participate in many reactions including a formal (4 + 1) cycloaddition with electron-deficient dienes. We have learned to control the relative stereochemistry of the newly created chiral carbons in this pro
