—— | 3-hydroxymethyl-2H-chromene-2-carboxylic acid ethyl ester | 1352639-81-6 | C13H14O4 | 234.252 |
A simple catalytic racemic synthesis of benzopyranes, benzothiopyranes and 1,2-dihydroquinolines is presented. The organocatalytic domino reactions between 2-heteroatom substituted aldehyde derivatives and ?,?-unsaturated aldehydes or ?,?-unsaturated cyclic ketones proceed with excellent chemoselectivity to give the corresponding products in good to high yields.
