Base-controlled diastereodivergent synthesis of (R)- and (S)-2-substituted-4-alkylidenepiperidines by the Wadsworth-Emmons reaction

(Chemical Equation Presented) Significant base and reaction time effects have been observed in the Wadsworth-Emmons reaction between a chiral 2-substituted-4-oxopiperidine and phosphonates. In the reactions carried out using a large excess of DBU as the b

Unexpected epimerization at C2 in the Horner-Wadsworth-Emmons reaction of chiral 2-substituted-4-oxopiperidines

The observed epimerization at C2 in the Horner-Wadsworth-Emmons (HWE) reaction of chiral 2-substituted-4-oxopiperidines has been investigated and, on the basis of the experimental results, a mechanism for this unexpected process has been propos

Study of the reaction of imines derived from (R)-glyceraldehyde with Danishefsky's diene

N-Benzylimines derived from conveniently protected (R)-glyceraldehyde underwent diastereoselective tandem Mannich-Michael reaction with Danishefsky's diene in the presence of Lewis acids. The temperature, catalyst and solvent dependence of the product rat
