Monoamine oxidase (MAO) was shown previously to undergo time-dependent inhibition by 5-(aminomethyl)-3-(4-methoxyphenyl)-2-oxazolidinone (3, X=N, Y=O, R=Me, R'=H), cis- and trans-5-(aminomethyl)-3-(4-methoxyphenyl)dihydrofuran-2(3H)-one (5, R=Me), and 4-(aminomethyl)-1-(4-methoxyphenyl)-2-pyrrolidinone (6, R=Me). Two approaches are taken in this article to test the hypothesis that the cause for this

Manganese(III)-promoted addition of various 1,3-dicarbonyl compounds to enol ethers or terminal enolesters, followed by hydrolysis of the resulting adducts and base catalyzed aldol cyclization provides an effective process for the synthesis of a wide range of fused and spiro 2-cyclopentenones.

practical reagent for the preparation of vinyl ether with good to excellent yield. This method efficiently effects methoxymethylenation or vinyl ether formation of enolizable, nonenolizable, and sterically hindered ketones. The complexation of Ti–Mg–CHOMe was facilitated, presumably, by THF dramatically increasing the feasibility; and scope of this protocol is to produce vinyl ethers which can be used
