Level 1 — Case 10 Nucleophile Versus Base Catalysisechanisms for amine-catalyzed reactions of carbonyl compounds involve acylium ion and ketene intermediates (the latter can only occur for acid halides containing α-hydrogens), but the actual role of the catalyst is still uncertain.

Level 2 — Case 19 Chelate-Controlled Carbonyl Addition Reactions SnCl. was employed, aldols . were obtained preferentially with selectivities higher than 95:5. Instead, the stereoisomers . were isolated with nearly total stereoselectivity when Me.AlCl (2 eq) was used to promote the reaction (Scheme 19.1a and b)..
