In this work, a new bis-succinimide (Bis-Su) compound 1-[4-(2,5-dioxopyrrolidin-1-yl)butyl]pyrrolidine-2,5-dione is prepared, identified and used as a green and efficient basic organo-catalyst for the promotion of the synthesis of arylidene malononitriles ArCH=C(CN)2 (Ar = C6H5, 4-ClC6H4, (E)-4-NO2C6H4CH=CH, etc.) and tetrahydrobenzo[b]pyrans I. Using this method, both of the reactions were performed under mild conditions, during short reaction times in high yields. The catalyst can also be recycled and reused several times without a considerable decrease in its activity. In the experiment, the researchers used 2-Methoxybenzaldehyde(cas: 135-02-4Product Details of 135-02-4)
2-Methoxybenzaldehyde(cas: 135-02-4) is used as a flavor agent in foods including nonalcoholic/alcoholic beverages, baked goods, chewing gum, confections, frozen dairy, fruit ices, hard/soft candy, instant coffee, tea, Jams, jellies, and milk products. It also has been used to obtain good enantioselectivities using Cu(OAc)(2)-bis(oxazolines) via hydrogen bonding in asymmetric Henry reaction.Product Details of 135-02-4
