The Br?nsted acid-catalyzed synthesis of primary amines from acetyl arenes and alkanes with C-C bond cleavage is described. Although the conversion from an acetyl group to amine has traditionally required multiple steps, the method described herein, which uses an oxime reagent as an amino group source, achieves the transformation directly via domino transoximation/Beckmann rearrangement/Pinner reaction. The method was also applied to the synthesis of γ-aminobutyric acids, such as baclophen and rolipram.

We present a general protocol for the formal Michael addition of acetone to α,β-unsaturated esters and amides, a transformation difficult to perform using current methods. The protocol comprises of an amidine catalyzed relay ring-opening and fragmentation
USE OF 1,3-DIOXIN-4-ONES AND THEIR RELATED COMPOUNDS IN SYNTHESIS. 27. NOVEL ASYMMETRIC HETERO-DIELS-ALDER REACTION USING CHIRAL SPIRO 5-METHYLENE-1,3-DIOXANE-4,6-DIONES HAVING 1-MENTHONE AT THE 2-POSITION

Diastereofacially selective hetero-Diels-Alder reaction of spiro (E or Z)-5-arylidene-1,3-dioxane-4,6-diones and 2-methoxypropene was studied.The dihydropyrans thus obtained were converted to optically active β-arylated δ-oxohexanoic acids.The diastereofa
