Abstract

This aldehyde has been synthesised by different methods4 View all references and is therefore of current interest.5 View all references It is commonly used as an important intermediate for the production of β-ionone, on which all industrial syntheses of vitamin A, β-carotene and related compounds are based. ... We report here new syntheses of citral 1 via 6-methyl-5-hepten-2-one 2. Noteworthy is the fact that only a few examples of the preparation of this ketone from ...
