Methyl 2,2'-dimethyl-4'-[2-(methyl-sulfan-yl)eth-yl]-1,3-dioxo-2,3-dihydro-1H,4'H-spiro-[isoquinoline-4,5'-oxazole]-4'-carboxyl-ate.

ABSTRACT: In the isoquinoline ring system of the title mol-ecule, C(18)H(20)N(2)O(5)S, the fused N-heterocyclic ring is distorted towards a half-boat conformation. The methyl formate moiety is disordered over two sets of sites with refined occupancies of 0.882 (5) and 0.118 (5). In the crystal, mol-ecules are linked via weak inter-molecular C-H⋯O hydrogen bonds into one-dimensional chains along [010].
