Selective formation of methylvinyl ketone (MVK) was attained over chrysotile, Mg3(OH)4Si2O5, through aldol condensation reaction between acetone and formaldehyde, the selectivity being 98 percent on both acetone and formaldehyde bases.Synthetic Co2+-substituted chrysotile, CoxMg3-x(OH)4Si2O5 (x= 0.15 or 0.9), catalyzed the reaction between acetone and methanol to give MVK and methylethyl ketone (MEK) with 75 percent selectivity on acetone basis.

One-pot synthesis of Robinson annulated 3-aryl-cyclohexenones from allyl alcohols and ketones using palladium is reported. Long chain aliphatic or aryl substitutions at the C1 position of allyl alcohol result in the formation of 1,5-diketone products. This simple one-pot method avoids the use of highly electrophilic vinyl ketones.
K2S2O8-promoted C-Se bond formation to construct α-phenylseleno carbonyl compounds and α,β-unsaturated carbonyl compounds

, p. 28902 - 28905 (2020/08/25)
A novel K2S2O8-promoted C-Se bond formation from cross-coupling under neutral conditions has been developed. A variety of aldehydes and ketones react well using K2S2O8 as the oxidant in the absence of catalyst and afford desired products in moderate to excellent yields. This protocol provides a very simple route for the synthesis of α-phenylseleno carbonyl compounds and α,β-unsaturated carbonyl compounds.

The asymmetric allylation of 1-pyrroline-5-carboxylic esters has been accomplished through a synergistic Pd/Cu catalyst system under mild reaction conditions. The mechanistic studies suggested that (1) nucleophilic attack is the enantiodiscriminating step; (2) the cooperative action of two chiral reactive species, N-metalated azomethine ylides and ?€-allylpalladium, is most likely responsible for its high reactivity and excellent enantioselectivity (up to >99% ee); and (3) the steric hindrance and electronic factors of the allylic electrophiles and imino ester substrates are crucial for the formation of the linear products. A series of 3,4-2H-pyrrole derivatives bearing a quaternary stereogenic center were easily synthesized in high yields and with high to excellent regioselectivity and enantioselectivity.
