Stereoselective Synthesis of Pyrido- and Pyrrolo[1,2-c][1,3]oxazin-1-ones via a Nucleophilic Addition-Cyclization Process of N,O-Acetal with Ynamides

An efficient asymmetric approach to access functionalized pyrido- and pyrrolo[1,2-c][1,3]oxazin-1-ones has been developed through a nucleophilic addition-cyclization process of N,O-acetal with ynamides. A number of substituted ynamides 8a-8o and 3-silyloxypyrrolidine or piperidine N,O-acetals 6a, 7 were amenable to this transformation, and the desired products 9a-9o, 10a-10m were obtained with excellent regioselectivities and outstanding diastereoselectivities. Moreover, chiral ynamides 14a-14f could also experience this addition-cyclization process to afford products 15a-15f in excellent yields.

A Modular Synthesis of 4-Aminoquinolines and [1,3] N-to-C Rearrangement to Quinolin-4-ylmethanesulfonamides

A copper-catalyzed regiocontrolled three-component reaction afforded diversified 4-aminoquinolines using nitriles, diaryliodoniums, and ynamides. The C7-substituted regioisomers were formed regioselectively when meta-substituted phenyliodonium salts were used. [1,3] N-to-C rearrangement of the products to quinolin-4-ylmethanesulfonamides and simultaneous deprotection of benzyl and sulfonamide group were newly developed. Finally, antimalarial CK-2-68 was successfully prepared.

Regio- and stereospecific synthesis of (E)-α-iodoenamide moieties from ynamides through iodotrimethylsilane-mediated hydroiodation

A facile approach to (E)-α-haloenamide moieties from ynamides using bromo- or iodotrimethylsilane is described. The simple protocol enables a regio- and stereospecific hydrohalogenation of the triple bond in gram-scale and provides a general entry for synthesis of novel enamide analogues.
