Natural retinoids, especially retinol, are present in all living organisms. They are known as fundamental mediators for many biological processes, e.g. vision, cellular growth, differentiation of epithelial tissue, reproduction, etc. Although retinol is an omnipotent compound, natural retinoids like all E, 9Z and dehydroretinoic acids are clearly more potent outside the retina and trigger gene expression via binding to nuclear retinoid receptors. Retinaldehyde occupies an intermediate position in this respect, with the ability to convert to both retinol and retinoic acid (RA). Retinol has an exceptional position among the retinoids, both in terms of production and its field of applications. In 1995, the sales of retinol reached US $ 500 million. Considering the interplay between the stereochemistry of retinoids and their biological activities, any synthetic approach to these compounds must meet the requirement of stereochemical control, in order to obtain the desired isomer in a highly stereoselective manner. Despite the recent achievements in the preparation of conjugated E/Z-dienes and trienes using a variety of synthetic procedures, there is still a need for versatile and efficient approaches to higher unsaturated E/Z-polyolefins with the appropriated configuration. This review covers the major synthetic literature on natural retinoids from 1990 to the present.
