Combining pot, atom and step economy (PASE) in organic synthesis. Synthesis of tetrahydropyran-4-ones†
Abstract
The combination of pot, atom and step economy (PASE) in the synthesis of organic molecules of medium complexity can lead to a significant ‘greening’ of a synthetic route. This is demonstrated by the synthesis of highly substituted tetrahydropyran-4-ones and is quantified by a series of recognised metrics, which demonstrate the efficiency of combining PASE over conventional synthetic strategies.
