Stereoselective Synthesis of 3-Substituted Cyclobutanols and Products Derived Therefrom
Dehmlow, Eckehard V.,Bueker, Sabine
, p. 2759 - 2764 (2007/10/02)
3-Substituted cyclobutanones 2 are prepared by alkene/dichloroketene cycloadditions and subsequent dehalogenation.Reduction with LiAlH(OtBu)3 furnishes cis-cyclobutanols 3 in 95-100percent selectivity.Mitsunobu inversion turned out to be the only practica
