The reaction of aldehydes, amines and alcohols usually leads to a series of equilibria from which isolation of one product is difficult to achieve. We have found that this three-component reaction can be controlled and directed in an exclusive manner toward the formation of the hemiaminal ether. A series of 33 hemiaminal ethers has been obtained in high yields, from different aldehydes, amines and alcohols, under very mild conditions just with molecular sieves as promoter.

Anodic oxidation of N-alkyltosylamides 1 in methanol containing KX (X = Br, I) gave two types of products, α-(tosylamino) aldehyde acetals 2 and pyrrolidine derivatives 3, and each of the products could selectively be formed by modifying the reaction conditions when the alkyl group on the nitrogen of 1 was not branched at its α-position. Namely, anodic oxidation ot N-(α-unbranched alkyl)tosylamides 1a-g in methanol containing NaOMe and KI at -10°C followed by further anodic oxidation at 25°C afforded 2 in good yields, while that of 1 in a two-layer system consisting of cyclohexane and water containing KOH and KBr under heating yielded solely 3. On the other hand, N-(α-branched alkyl)tosylamides 1h-j gave always 3. Two types of reaction routes leading to each of the products were proposed.
