Reaction was proceeding via three component reaction by utilizing various aldehyde, malononitrile and ethylacetoacetate at room temperature. All Synthesized products were confirmed by Mass, 1H-NMR, IR and Melting point. Mild reaction conditions, excellent yields, easy isolation of products, no column chromatographic separation, reusability of reaction media.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9786206151517\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9786206151517","offer_id":46492322267461,"sku":"9786206151517","price":43.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/4dbe2bfa-ed87-4f67-926c-0ca227a0ad64.jpg?v=1765348847","url":"https:\/\/shop.autorenwelt.de\/products\/multicomponent-synthesis-of-4h-pyran-3-carboxylate-derivatives-von-dhaval-b-patel","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
