Direct anodic (thio)acetalization of aldehydes with alcohols (thiols) under neutral conditions, and computational insight into the electrochemical formation of the acetals

A versatile protocol for the production of acetals/thioacetals by means of direct electrochemical oxidation is developed here under neutral conditions, providing (thio)acetals with good functional group tolerance and a wide scope for both aldehydes and (thio)alcohols. DFT calculations reveal that direct electron transfer from the anode plays a key role in carbonyl activation during this acid free acetalization process.

Stereoselective approaches to the total synthesis of (6R,4′S, 6′R)-cryptofolione

Total syntheses of cryptofolione were accomplished by two different routes via a common intermediate that underwent a cross-metathesis (CM) reaction with a vinyl lactone. The intermediate was prepared by coupling of an acyl anion equivalent with a chiral allyl epoxide synthon, or by Prins cyclization of a trans-cinnamaldehyde with a chiral homoallylic alcohol. Goniothalamin was obtained as a cross-metathesis product of the diacetate and vinyl lactone. Georg Thieme Verlag Stuttgart.

Trichloromelamine (TCM) - Catalyzed efficient and selective thioacetalization of aldehydes and transthioacetalization of acetals and oxathioacetals under mild reaction conditions

Trichloromelamine was used effectively as a catalyst for thioacetalization of aldehydes and transthioacetalization of acetals and oxathioacetals under mild and almost neutral reaction conditions. By this method, aldehydes, acetals, and oxathioacetals were selectively protected in the presence of ketones as their 1,3-dithiolanes or 1,3-dithianes. Copyright Taylor & Francis Group, LLC.
