An Efficient Route to Chiral trans-2,5-Dialkylpyrrolidines via Stereoselective Intramolecular Amidomercuration

Takahata, Hiroki,Takehara, Hiroyuki,Ohkubo, Naoki,Momose, Takefumi

, p. 561 - 566 (2007/10/02)

An intramolecular amidomercuration of α-butylated 4-pentenylcarbamate 5 predominantly provided trans-2,5-disubstituted pyrrolidine 6, which was elaborated to chiral trans-5-butyl-2-alkylpyrrolidines 10 and 13, constituents of ant venoms.
