A Stereocontrolled Synthesis of 2,3,5-Trisubstituted Tetrahydrofurans from Aldolized γ-Diketones via Cyclization-reduction Process

Mukaiyama, Teruaki,Hayashi, Masaji,Ichikawa, Junji

, p. 1157 - 1160 (1986)

2,3,5-Trisubstituted tetrahydrofurans with cis-2,5 relationship are obtained in good yields by cyclization of the silyl ethers of aldolized γ-diketones followed by successive stereocontrolled reduction with triethylsilane in the presence of trityl perchlo
