1957 Joined the Schering Corporation as a Medicinal Chemist. In a roughly 10 year period he and his research group synthesized and patented 5 drugs that were subsequently marketed (trichlormethiazide, diazoxide, halazepam, quazepam and flutamide).
Formulated operational schemes for analogue synthesis in drug design published in 1972 and 1977 known as “”Topliss Decision Trees.”” The methodology has been widely adopted by medicinal chemists and is still in use. It has been extensively cited in the literature and in text books on medicinal chemistry or drug design.
