- Neutral Organic Super Electron Donors Made Catalytic
-
Neutral organic super electron donors (SEDs) display impressive reducing power but, until now, it has not been possible to use them catalytically in radical chain reactions. This is because, following electron transfer, these donors form persistent radical cations that trap substrate-derived radicals. This paper unlocks a conceptually new approach to super electron donors that overcomes this issue, leading to the first catalytic neutral organic super electron donor.

- An atom-economic and selective ruthenium-catalyzed redox isomerization of propargylic alcohols. An efficient strategy for the synthesis of leukotrienes
-
Catalytic ruthenium complexes in conjunction with an indium cocatalyst and Broensted acid isomerize primary and secondary propargylic alcohols in good yields to provide trans enals and enones exclusively. Readily available indenylbis(triphenylphosphine)ruthenium chloride, in the presence of indium triflate and camphorsulfonic acid, gives the best turnover numbers and reactivity with the broadest range of substrates. Deuterium labeling experiments suggest that the process occurs through propargylic hydride migration followed by protic cleavage of the resultant vinylruthenium intermediate. Application of this method to the synthesis of leukotriene B4 demonstrates its utility and extraordinary selectivity.

- 4-(Trialkylsilyl)oxybut-2-ynals as dienophiles in the Diels-Alder synthesis of α-(hydroxymethyl)benzaldehydes
-
The α-(hydroxymethyl)benzaldehyde derivative 2 has been synthesized by heating ynal 3 with diene 5, which produced the α-(silyloxymethyl)benzaldehyde 6 by a Diels-Alder/retro-Diels-Alder process, followed by methylation, thioacetalization, and removal of the silyl protecting group. Decarbonylation of α-(silyloxymethyl)benzaldehydes 6 and 10 takes place readily in the presence of zinc(II) chloride or para-toluenesulfonic acid.
