Development of enantioselective synthetic routes to (-)-Kinamycin F and (-)-lomaiviticin aglycon
The development of enantioselective synthetic routes to (-)-kinamycin F (9) and (-)-lomaiviticin aglycon (6) are described. The diazotetrahydrobenzo[b] fluorene (diazofluorene) functional group of the targets was prepared by fluoride-mediated coupling of

Conversions of allyl ethers in a superbasic medium
Conversions of alkyl allyl and terpenoid allyl ethers in a superbasic medium (dimethyl sulfoxide-potassium hydroxide) are studied. The ethers with an unbranched alkyl substituent isomerize into propenyl ethers, the ethers with a branched unsaturated substituent decompose to give a hydrocarbon, and diallyl ethers isomerize into allyl vinyl ethers whose Claisen rearrangement gives rise to aldehydes.

MOLYBDENUM CATALYZED ELIMINATIONS OF ALLYLIC ACETATES. NEW DIENE SYNTHESIS
Allyl acetates smoothly eliminate the elements of acetic acid in the presence of O,N-bis(trimethylsilyl)acetamide and molybdenum hexacarbonyl; a simple sequence permits elaboration of saturated aldehydes into α,β,γ,δ-dienoates which resulted in a four step synthesis of trichonine.
