i restate my comment that the article contains too much jargon and is too technical this should not mean that material gets thrown out in my view wiki articles cannot be too technical if the underlying principles are worked out the current article lacks many links links to concepts that should be included nucleophilic addition concepts mentioned in the text but not linked antiperiplanar chair conformation chemical equilibrium diethyl malonate benzaldehyde methylene malonate sodium ethoxide stereoselective olefin hyperconjugation stoichiometry bond length diastereoselectivity chirality stereocenter epimer pentane interference rotamer links to these articles will really help the average reader concepts mentioned in text but not explained pi orbital triphenylmethyllithium bbn cl dipea cy bcl diaxial interaction allylic strain diastereoface polyketide stereoarray also many aldol variations are already contained in separate articles other variations branch of in the aldol condensation reaction alone so i have no problem with subarticles for variations
