Crystal structures of 4-methyl-2-oxo-2H-chromene-7,8-diyl di­acetate and 4-methyl-2-oxo-2H-chromene-7,8-diyl bis­(pent-4-ynoate)

In the structures of the two title coumarin derivatives, C(14)H(12)O(6), (1), and C(20)H(16)O(6), (2), one with acetate and the other with pent-4-ynoate substituents, both the coumarin rings are almost planar. In (1), both acetate substituents are significantly rotated out of the coumarin plane to m...
