- The reaction involved a [4+2] cyclization of α,β-unsaturated acyl chlorides with specific electron-deficient alkenes.
- This process resulted in the formation of spirocarbocyclic oxindoles, which are unique cyclic compounds.
Article Abstract
Cinchona alkaloids were used as Lewis base catalysts in the title reaction. The [4+2] cyclization of α,β-unsaturated acyl chlorides with electron-deficient alkenes derived from oxindole gave the corresponding spirocarbocyclic oxindoles.

2-Deoxy-β-glycosides are essential components of natural products and pharmaceuticals; however, the corresponding 2-deoxy-β-glycosidic bonds are challenging to chemically construct. Herein, we describe an efficient catalytic protocol for synthesizing 2-deoxy-β-glycosides via either IPrAuNTf-catalyzed activation of a unique 1,2--positioned C2--propargyl xanthate (OSPX) leaving group or (PhO)PAuNTf-catalyzed activation of a 1,2--C2--alkynylbenzoate (OABz) substituent of the corresponding thioglycosides. These activation processes trigger 1,2-alkyl/arylthio-migration glycosylation, enabling the synthesis of structurally diverse 2-deoxy-β-glycosides under mild reaction conditions.

Oxidation of thia-pentapyrrane S-P4 with terminal β-linked pyrrole and thiophene units in the presence of various metal ions has been found to afford distinct porphyrinoids. Specifically, N-confused thiasapphyrin (1), Cu(III) norrole (2), neo-confused phlorin (3), and p-benzinorrole (4) were obtained, when S-P4 was oxidized with p-chloranil in acetonitrile in the presence of Ni2+, Cu2+, Cd2+, and Co2+, respectively. The structures of 1-4 have been clearly elucidated by NMR spectroscopy, HRMS, and X-ray crystal diffraction (for 2-4).

A thiazolo-pyrimidinone derivative library was developed through a facile solid-phase synthesis method. For the reaction, the thiazolo[4,5-]pyrimidin-7(6)-one structure was synthesized through efficient Thorpe-Ziegler and cyclization reactions. The thiazolo[4,5-]pyrimidin-7(6)-one derivative library with a diversity of three had a total of four synthesis steps and 57 compounds.

Herein a novel and robust methodology to spiroimidazolidinones has been developed under a mild reaction. The reaction of (Z)-2-azido-3-phenylacrylic acids , aldehydes , amines , isocyanides , and isocyanides produced regioselectively spiroimidazolidinones in 71-88% yields via a sequential Ugi 4CR/Pd(0) catalyzed azide-isocyanide coupling/cyclization/rearrangement/hydroxylation reaction. Furthermore, the easily accessible starting materials, high bond-forming efficiency, and broad substituent tolerance make this strategy useful in synthetic and medicinal chemistry.
