Green preparation method α - hydroxyketone

The invention relates to a green preparation method of alpha-hydroxyketone. The method comprises the following steps: adding ketone, iodine, 1,4-diazabicyclo[2.2.2]octane and methanol into a glass reaction bottle in sequence; then stirring and reacting for 14 to 30h at room temperature in an air atmosphere under the irradiation of a 23W compact type fluorescent lamp, so as to obtain a reaction mixture; carrying out silica gel column chromatographic separation to obtain the pure alpha-hydroxyketone. The green preparation method provided by the invention has the characteristics of greenness, high efficiency, simplicity in operation, moderate conditions, wide applicability and easiness for industrialization.

Halogen-bonded iodonium ion catalysis: A route to α-hydroxy ketones: Via domino oxidations of secondary alcohols and aliphatic C-H bonds with high selectivity and control

A domino synthesis of α-hydroxy ketones has been developed from benzylic secondary alcohols employing catalytic iodonium ions stabilized by DMSO. The reaction proceeds through an unprecedented sequential oxidation of alcohols to ketone and its α-hydroxylation in a controlled manner. The spectroscopic evidence establishes the possibility of formation of a stable halogen-bonded adduct between DMSO and iodonium ions.

Switching regioselectivity in crossed acyloin condensations between aromatic aldehydes and acetaldehyde by altering n -heterocyclic carbene catalysts

An unprecedented high level of regioselectivities (up to 96%) in the intermolecular crossed acyloin condensations of various aromatic aldehydes with acetaldehyde was realized by an appropriate choice of N-heterocyclic carbene catalysts.(Figure Presented)

Synthesis and antifungal activity of new azole derivatives containing an N-acylmorpholine ring

A series of azole derivatives carrying an N-acylmorpholine ring are described. The compounds were chemically designed to simulate the lanosterol D ring, taking advantage of the conformational preferences of 2-alkyl-1- acylmorpholines. Three structural variables, the nature of the N-benzoyl group, the phenyl substituents, and the degree of oxidation at carbon 2 of the morpholine, were optimized for maximum activity. Only the (5R,6R) isomers showed antifungal activity. Cyclic hemiacetal (-)-39a (UR-9746) and cyclic ether (-)-41 (UR-9751) were selected for further development. In vitro, (-)- 41 was clearly more active than (-)-39a and somewhat less active than the acyclic counterpart (-)-7. In vivo activity was assessed by a systemic (mouse) and a vaginal (rat) candidosis model. In the former, (-)-39a, (-)- 41, and (-)-7 at 1 mg/kg given 1, 4, and 24 h postinfection displayed 90- 100% protection from mortality on day 9. Compound (-)-39a was slightly more potent than (-)-41 and similar in potency to (-)-7. The three compounds were superior in potency to fluconazole and similar in potency to SCH-42427 in this test. In the vaginal model, (-)-39a and (-)-41 given daily during 3 days after infection at 0.5 mg/kg showed high levels of protection on days 10 and 15. At 0.25 mg/kg, (-)-39a was slightly more potent than SCH-42427 and (-)-7 and superior in potency to (-)-41 and fluconazole in this model. Preliminary 28-day toxicity tests at 100 mg/kg/day po in rats indicated no or very mild adverse effects for the two UR compounds.
