(4′S)‐4′‐Ethyl‐3′,10′‐dioxo‐3′,4′,7′,8′‐tetrahydrospiro[1,3‐dioxolane‐2,6′‐1′H,6′H‐pyrano[3,4‐f]indolizin]‐4′‐yl N‐(1‐phenylethyl)carbamate

The title compound, C24H26N2O7, is an inter­mediate in the resolution of a tertiary alcohol using a chiral isocyanate reagent. On the basis of the unchanging S configuration of the chiral C atom introduced by the isocyanate reagent, the chiral centre on the tricyclo ring system is shown to adopt an S configuration. In the crystal structure, N—H⋯O hydrogen bonds link the mol­ecules into chains.
