Synthesis of β-and β,β-substituted Morita-Baylis-Hillman adducts using a two-step protocol

The synthesis of a large number of β-and β,β-substituted keto esters was successful by the use of the Knoevenagel condensation reaction. The stereoselectivity of these reactions was improved by alteration of various substituent groups. Although there were

Preparation of α-functionalized alkenylmagnesium reagents via a halide-magnesium exchange

A general preparation of alkenylmagnesium derivatives bearing an electron-withdrawing function in the α-position (Y=CN, CO2R, CONR2, SO2Ph) has been made possible by using a low temperature (-40 to -30°C) bromine-magnesium exchange with i-PrMgBr in THF. This reaction has also been used to prepare 5-magnesiated-1,3-dioxin-4-one derivatives bearing an alkoxy substituent in β-position to the carbon-magnesium bond.

Preparation of functionalized alkenylmagnesium bromides via a bromine- magnesium exchange

α-Bromonitriles, such as 1, 2 or the α-bromosulfone 3, undergo a smooth bromine-magnesium exchange with isopropylmagnesium bromide furnishing new functionalized organomagnesium species which react smoothly with various electrophiles like Me3SiCl, Bu3SnCl, allyl bromides, aldehydes, ketones or acid chlorides providing the expected products of type 7, 8 or 9.

ALUMINA SUPPORTED POTASSIUM FLUORIDE PROMOTED REACTION OF NITROALKANES WITH ELECTROPHILIC ALKENES: SYNTHESIS OF 4,5-DIHYDRO FURANS AND ISOXAZOLINE N-OXIDES.

The reaction of secondary nitro alkanes 1 with α,β-unsaturated ketones 2 in the presence of alumina-supported potassium fluoride in acetonitrile gave 4,5-dihydrofurans 3 in high yields; 1-nitropropane reacted with 2 to give a mixture of 4,5-dihydrofurans and furans.Nitroalkenes 17 reacted with nitroalkanes to give isoxazoline N-oxides 18 and 19 in good overall yields.

Lithio Styryl Sulfone as an Acyl Anion Synthon

Lithio styryl sulfone, which was shown to be an acyl anion synthon, reacted with various electrophiles; the products were rearranged by treatments with m-chloroperbenzoic acid to give acyl benzyl sulfones in good yields.
