The synthesis and stereochemistry of desacetoxymatricarin and the stereochemistry of matricarin
Tetrahedron, 1969Abstract Desacetoxymatricarin (IV), a sesquiterpene lactone found in the genus Artemisia and in the form of 8-hydroxy and acetoxy derivatives in the genus Achillea, has been synthesized from α-santonin by a sequence that allows assignment of the full stereochemistry. The stereochemistry of matricarin (V) has also been determined.

This review article, based on a lecture delivered in Madras in 1985, is an account of the author's experience in the working out of the molecular structure and conformation of the collagen triple‐helix over the years 1952–78. It starts with the first proposal of the correct triple‐helix in 1954, but with three residues per turn, which was later refined

The relationship between fundamental and applied is often uneasy, particularly in modern political climates. A familiar political view, aimed negatively at the scientific community, is that the former is a waste of money whereas the latter gives value for investment.

This short chapter is really just to set the scene for the rest of the book, highlighting the importance of stereochemistry and the approaches we can use to study the topic. Don't worry if the new material appears daunting at this point. We'll go through it slowly in the relevant chapters.

This chapter reviews stereochemistry. It begins by differentiating between enantiomers and chiral compounds. Two structures that are not identical but are mirror images of each other are called enantiomers. Structures that are not superimposable on their mirror image, and can therefore exist as two enantiomers, are called chiral.
