  Diastereoselective intramolecular hetero Diels–Alder approach towards polycyclic heterocycles

  摘要：

  Several different heterocyclic aldehydes, derived from pyrazole. pyrimidine, pyridine, indole and thiazole, were converted to polyheterocyclic compounds containing four to seven rings. The key steps in the sequence were a Knoevenagel condensation of the aldehyde and a heterocyclic carbonyl compound, such as pyrazolone and isoxazolone, followed by an intramolecular hetero Diets-Alder reaction. Most final products were isolated with high yield and diastereoselecivity. The isoxazolo fused cycloadducts formed interesting spiro-adducts upon heating. The cis nature of the bridging hydrogens of the heterocycles was evidenced by X-ray diffraction analysis.(dagger) (C) 2002 Elsevier Science Ltd. All rights reserved.

  Abstract Intramolecular [4+2] cycloaddition reactions of N-aryl imines generated in situ from anilines and the S-allyl derivatives of pyrazole aldehydes have been carried out in the presence of catalytic amounts of BiCl3 to provide the corresponding hexahydropyrazolo [4′,3′:5,6]thiopyrano[4,3-b]quinolines in excellent yields. The reactions are highly diastereoselective and the only cis products are

  The synthesis of novel polycyclic thiopyrano coumarin/chromone frameworks through intramolecular domino Knoevenagel hetero Diels-Alder reactions of 4-hydroxy coumarin and its benzo-analogous with S-prenylated aromatic aldehydes was studied. A high degree of chemoselectivity was achieved by the application of microwave irradiation and a solid support. (c) 2006 Elsevier Ltd. All rights reserved.
