Straightforward Superbase-Mediated Reductive O-Phosphorylation of Aromatic and Heteroaromatic Ketones with Red Phosphorus in the Superbase Suspension KOH/DMSO(H2O)

open access: yesMolecules
It was shown for the first time that diaryl(hetaryl)ketones are capable of directly phosphorylating with red phosphorus in the superbase suspension KOH/DMSO(H2O) at 85 °C for 1.5 h to afford potassium bis(diaryl(hetaryl)methyl)phosphates that were ...

Synthetic Studies Directed Toward Streptenol D: Enantioselective Preparation of the 3,5-diacetoxy-6\u3cem\u3eE\u3c/em\u3e,8\u3cem\u3eE\u3c/em\u3e-decadiene Segment [PDF]

open access: yes, 1998
The enantioselective preparation of 2-(3′R,5′R-diacetoxy-6E,8E-decadienyl)-1,3-dioxane, (+)-13, is described. This synthesis of the skeleton of streptenol D utilizes the ability of a diene-complexed (tricarbonyl)iron unit to serve as a protecting and ...
