Enhanced Reactivity of Zinc Enolates over Lithium Enolates in Asymmetric Nitroolefination.

Chemical and Pharmaceutical Bulletin (1994)

Kaoru Fuji Takeo Kawabata Y. NANIWA T. OHMORI Manabu Node

Zinc enolates derived from an ester and a lactone, 1 and 4, were found to have enhanced reactivity over the corresponding lithium enolates in asymmetric nitroolefination.

Enantioselective Creation of Quaternary Carbon Centers through Addition- Elimination Reaction: Asymmetric Nitroolefination of 3-Substituted 2-Oxindoles

Heterocycles (1998)

Kaoru Fuji Takeo Kawabata T. OHMORI Muhong Shang Manabu Node

Nitroolefination of 3-substituted 2-oxindoles with nitroenamine (5) afforded the corresponding products having quatemary carbon centers with high ee in good yield.Application of this method to concise syntheses of (-)- esermethole ( 24) and (-)-pseudophrynaminol ( 28) is described.Asymmetric creation of quatemary carbon centers is a matter of infinite importance in organic synthesis.'Nearly ten years ago, we reported high asymmetric induction through addition-elimination process to construct a chiral carbon at the a-position of 6-lactone~,~ and the products were used as chiral building
