Abstract
A new type of carotenoid has been synthesized with a 2Hpyran ring placed in the polyene chain. This compound was successively elongated by Wittig reactions. The pyran-carotenoids obtained show a significant increased A max compared with carotenoids lacking the pyran ring. A further remarkable bathochromic shift was observed upon protonation to pyranium-carotenoids. The pyranium ring is the distinctive feature of anthocyanidin dyes and has now become an internal part of carotenoids. © 2010 Wiley-VCH Verlag GmbH & Co. KGaA.
