Efficient catalyst for tandem solvent free enantioselective Knoevenagel-formal [3+3] cycloaddition and Knoevenagel-hetero-Diels-Alder reactions

In this study a highly efficient catalyst has been observed for tandem solvent free enantioselective Knoevenagel-formal [3+3] cycloaddition and Knoevenagel-hetero-Diels-Alder reactions. Thus, the synthesis of bicyclic tetrahydro-2H-chromen-5(6H)-one and tricyclic octahydro-2H-benzo[c]-chromen-1(6H)-one derivatives with enantioselectivity up to ee 99% has been achieved in the presence of a chiral Lewis acid assisted Bronsted acid (LBA), titanium-isopropoxy-(S)-BINOLate under solvent free conditions. The stereochemistry of the tricyclic product 10 has been further supported by single crystal X-ray analysis. This domino powerful strategy combines both the economic and environmental aspects of organic chemistry, which are necessary for academic and industrial applications.

Environmentally benign, one-pot synthesis of pyrans by domino Knoevenagel/6π-electrocyclization in water and application to natural products

In water medium, environmentally benign, facile, and efficient synthesis of pyrans was achieved in good yields by the reactions of a variety of cyclic 1,3-dicarbonyls with several α,β-unsaturated aldehydes. The key strategy was a formal [3+3] cycloaddition by domino Knoevenagel/6π- electrocyclization. This methodology was applied to the synthesis of biologically interesting pyranocoumarin, pyranoquinolinone, and pyranonaphthoquinone derivatives along with selected natural and non-natural products.
