Abstract
A full account of the total synthesis of ouabagenin and ouabain is described. A highly stereocontrolled anionic cycloaddition for the rapid construction of the basic steroid skeleton is a pivotal conversion for the whole strategy. A careful study was needed to establish the order and the sequence of functional group manipulations. Specific conformational features of the ouabain skeleton allowed us to overcome a few stereochemical problems. Degradation studies on ouabain provided an ultimate proof for a key intermediate, which is used as a relay. Late stage butenolide formation and glycosidation yielded ouabain.

Abstract
A real turn-on: The emission intensity of heterocycle 1 increases upon binding to Pb(2+). Thus, 1 acts as a small-molecule "turn-on" fluorescent sensor for lead. The sensor is highly selective and is functional over a wide range of pH values.
