“My students learned how submitting optimised queries enhances the

quality of the retrieved hits.

One issue for me is the lag-time between publication

and entry into the database“

“SPRESIweb is a great database for reaction searches. Our synthesis chemists use it intensively for synthesis planning … ”

IPB Halle

“I use it parallel to SciFinder, when I have problems finding a reaction, because SPRESIweb allows better

definition of reaction query features.

Unfortunately I cannot find polymer reactions …”

“I like most the structure-based searches, they are very helpful as starting point for my

synthesis projects … additionally, I like the ability of choosing certain molecules and search for them as product / reactant.”

“Because of the convenient licensing model, we use it at our institute to train our

undergraduate students in structure and reaction query submission before giving

them access to more expensive services”

ConclusionsConclusions

User friendly :• web application with online access, IP login, no installation, convenient licensing model

Intuitive:• clear interface, links for easy navigation, quick help

Excellent for reaction searches:• synthesis planning tool, name reactions, advanced query features

Lag-time between publication and database update

Selective, no polymers

… I found SPRESIweb to be an excellent database. While obviously selective, it will very likely produce unique results. The search interface is very intuitive and easy to learn. It could be a very reasonable alternative for introducing structure searching in smaller institutions …
