TL;DR: The title compound of C 13 H 15 O 7 P as discussed by the authors consists of two condensed rings, namely, a pyranoid ring with an axially attached partially disordered dimethoxyphosphoryl group and a benzene ring.
Abstract: The title compound, C 13 H 15 O 7 P, consists of two condensed rings, namely, a pyranoid ring with an axially attached partially disordered dimethoxyphosphoryl group and a benzene ring. The conformation of the pyranoid ring is halfway between half-boat and half-chair, and the fusion of the rings does not exert significant influence on the planarity of the benzene ring.

TL;DR: In this paper, a series of 2-substituted-4-(2-pyridyl)benzopyran analogues 6a-e have been prepared in 20-34% overall yields by the reductive condensation of 2.
Abstract: A series of 2-substituted-4-(2-pyridyl)benzopyran analogues 6a-e have been prepared in 20-34% overall yields by the reductive condensation of 2-substituted-3,4-dihydro-2H-1-benzopyran derivatives 5a-e with pyridine, as a key step.
