Stereoselective Synthesis of Highly Functionalized Structures from Lactate-Derived Halo Ketones
摘要:
Highly diastereoselective (i-PrO)(2)TiCl2-mediated aldol reactions from lactate-derived alpha'-halo alpha-silyloxy ketones and subsequent treatment of the resultant aldols with a wide range of nucleophiles furnishes highly functionalized arrangements useful in natural product syntheses.
