2-chiral induction of the conjugate addition of boronic acids to enantiopure α,β-unsaturated ketones and esters without competition from the Mirozoki–Heck reaction. Bedford's palladacycle was found to control the stereoselectivity without the need for additional chiral ligands. We report that the PdII-catalyzed conjugate additionreaction between boronic acids and acyclic ketones or esters that bear a hydroxyl

Oxidative cleavage of a series of glycols using NaIO4 on silica gel in the presence of a series of stabilized ylides provides access to a number of synthetically useful alkenes. The ease and general utility of this reaction is demonstrated here using several carbohydrates and amino acid derived glycols.

Isopropenyl copper reacts 1,4 with enones derived from glyceraldehyde acetonide with ANTI selectivity, whereas isopropenyl lithium also gives predominantly 1,4 product but with SYN selectivity.
