• Organotellurides as a source of organometallics: application in the synthesis of (+/−)-frontalin

  A masked lithium homoenolate, generated by tellurium/lithium exchange, was reacted with epoxides. The lithium compound was also converted into other organometallics such as Grignard, and cuprates and the reactivity of those organometallics with epoxides was evaluated. The same building block was employed in the synthesis of (+/−)-frontalin.

• Nonracemic frontalin via copper- and palladium-based skeletal construction and the asymmetric dihydroxylation
  作者：Braulio Santiago、John A. Soderquist

  日期：1992.10

  The new higher order organocuprate, Li2Cu(CN)(C(OMe):CH2)2, prepared through a Sn --> Li --> Cu transmetalation sequence, was found to efficiently couple with allyl bromide producing 2-methoxy-1,4-pentadiene (3) which is efficiently converted to the ketal 4. Hydroboration of 4 with 9-BBN-H and the selective oxidation of this adduct with trimethylamine N-oxide (TMANO) produces 9-oxa-10-borabicyclo[3.3.2]decane 5, which undergoes Pd-catalyzed cross coupling with 2-bromopropene producing 6, thereby accomplishing the construction of the frontalin carbon skeleton in 63% overall yield from allyl bromide. The Os-based dihydroxylation of 6 followed by ketalization either produces the racemic pheromone ((+/-)-1) or, with the Sharpless catalytic asymmetric dihydroxylation (dihydroquinine ligand) procedure, results in the selective formation of the S enantiomer in 35% ee. The de determined from the C-13 NMR spectra of the diastereomeric Mosher's monoesters (9) was found to provide useful corroborative information on the optical purity of the intermediate 1,2-diols 7.
