Usage

Synthesis

To a four-necked flflask, equipped with a mechanical stirrer, a reflflux condenser with a nitrogen inlet, a thermometer, and a pressure-equalizing dropping funnel, was added 36 g (0.30 mol) of acetone and 41.4 g (0.41 mol) of triethylamine under a nitrogen atmosphere. To this mixture, stirred at room temperature under nitrogen, was added via the dropping funnel 43.2 g (0.40 mol) of chlorotrimethylsilane over 10 min. ?The flflask was then immersed in a water bath and the contents were warmed to 35°C.?The water bath was removed and the dropping funnel was charged with a solution of 60 g (0.40 mol) of sodium iodide in 350 mL of acetonitrile. This solution was added to the stirred mixture in the flflask at such a rate that the temperature of the reaction was maintained at 34–40 °C without external heating or cooling. The addition required approximately 1 h. When the addition was complete, the reaction mixture was stirred for a further 2 h at room temperature. The contents of the flflask were then poured into ice-cold water, and the aqueous mixture was extracted three times with pentane. After extraction, the organic layer was dried over potassium carbonate and then concentrated with a rotary evaporator under reduced pressure. The crude product was a mixture of 97% of the desired silyl enol ether and 3% of acetophenone, as shown by gas chromatography. The crude product was distilled in a Claisen flflask at a pressure of about 40 mm. After a small forerun (about 3 g), 52.3 g (91%) of silyl enol ether, bp 124–125.5°C, was obtained. The purity of this material was approximately 98%, as judged by gas chromatography and 1 H NMR spectroscopy.

All at once arrangement of both oxygen atoms of dioxygen into aliphatic C(sp3)-C(sp3) bonds for hydroxyketone difunctionalization

Both β- and γ- hydroxyketone structures are important units in biologically active molecules, synthetic drugs and fine chemicals. Although there are some routes available for their manufacture from pre-functionalized groups on one or two matrix molecule(s), the approaches to simply and simultaneously deposit two oxygen atoms from dioxygen into two specific C(sp3) positions of pure saturated hydrocarbons have rarely succeeded because they are involved in the targeted activation of three inert C-H σ bonds all at once. Here, we show that a TiO2-CH3CN photocatalytic suspension system enables the insertion of dioxygen into one C(sp3)-C(sp3) bond of strained cycloparaffin derivatives, by which difunctionalized hydroxyketone products are obtained in a one-pot reaction. With the cleavage event to release strain as the directional driving force, as-designed photocatalytic reaction systems show 21 examples of β-hydroxyketone products with 31%–76% isolated yields for three-membered ring derivatives and 5 examples of γ-hydroxyketone products with 30%–63% isolated yields for four-membered ring substrates. 18O isotopic labeling experiments using 18O2, Ti18O2 and intentionally added H218O, respectively, indicated that both oxygen atoms of hydroxyketone products were exclusively from dioxygen, suggesting a previously unknown H+/TiO2-e? catalyzed arrangement pathway of the hydroperoxide intermediate to convert dioxygen into hydroxyketone units.

The invention provides a synthesis method for a beta-hydroxy-ketone compound shown in a formula (III). The method comprises the steps that substitute vinyl acetate shown in a formula (I), a substitute alcohol compound shown in a formula (II) and an oxidizing agent are mixed to obtain reaction liquid, and the reaction liquid reacts for 2-12 hours at the temperature of 20 DEG C-120 DEG C, and then is treated to obtain the beta-hydroxy-ketone compound. The method is safe and environmentally friendly, and is a new path for synthesizing the beta-hydroxy-ketone compound containing various substituents, the substrate adaptability is good, and the reaction operation is easy.

The Stereochemical Course of the α-Hydroxyphosphonate-Phosphate Rearrangement

The phosphonate-phosphate rearrangement is an isomerisation of α-hydroxyphosphonates bearing electron-withdrawing substituents at the α-carbon atom. We studied the stereochemical course of this rearrangement with respect to phosphorus. A set of four diastereomeric α-hydroxyphosphonates was prepared by a Pudovik reaction from two diastereomeric cyclic phosphites. The hydroxyphosphonates were separated and rearranged with Et3N as base. In analogy to trichlorphon, which was the first reported compound undergoing this rearrangement. All four hydroxyphosphonates could be rearranged to 2,2-dichlorovinyl phosphates. Single-crystal X-ray structure analyses of the α-hydroxyphosphonates and the corresponding phosphates allowed us to show that the rearrangement proceeds with retention of configuration on the phosphorus atom.
