Abstract

In the title compound, C(20)H(29)NO(8)S, the two five-membered rings adopt envelope conformations (with an O atom at the flap in each case), while the six-membered pyran ring displays a twist-boat conformation. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds into a supra-molecular chain running along the a axis.
