TL;DR: The complex TpW(NO)(PMe3)(eta(2)-anisole) is combined with acrolein or methyl vinyl ketone and various nucleophiles to generate novel chromen complexes that may be further elaborated by protonation and nucleophilic addition to generate chroman analogues with increased saturation and stereocenters.
Abstract: The complex TpW(NO)(PMe3)(η2-anisole) is combined with acrolein or methyl vinyl ketone and various nucleophiles to generate novel chromen complexes. These complexes may be further elaborated by protonation and nucleophilic addition to generate chroman analogues with increased saturation and stereocenters. Treatment with various oxidants effects the decomplexation of the chromen.

TL;DR: Several Baylis-Hillman adducts were prepared by the reaction of appropriate arylaldehydes with methyl vinyl ketone in the presence of imidazole and a catalytic amount of L-proline, in 55-90% yields as mentioned in this paper.
Abstract: Several Baylis-Hillman adducts were prepared by the reaction of appropriate arylaldehydes with methyl vinyl ketone in the presence of imidazole and a catalytic amount of L-proline, in 55–90% yields. An easy transformation of these adducts into 1,5-diarylpyrazoles was achieved using microwave irradiation (400 W) with short reaction times (1–3 min) and high yields (80–91%).

TL;DR: In this paper, a chiral ferrocenophane phosphines featuring only central chirality in good yields were obtained by the reaction of the corresponding chiral alcohol, 1,1′-[(1R)-1-hydroxy-1,3-propanediyl]ferrocene, and diarylphosphines in the presence of chlorotrimethylsilane and sodium iodide.

TL;DR: Asymmetric Michael reactions of α-substituted β-keto esters with methyl vinyl ketone catalyzed by 10 mol% of sodium 2′-[2-(2methoxyethoxy)ethoxy]-1,1′-binaphthalen-2oxide gave the optically active adducts quantitatively in up to 64% enantiomeric excess.
