Total Synthesis of C31-Methyl Ketone Apocarotenoids: Sintaxanthin and (3R)-3-Hydroxysintaxanthin

The previously undescribed (all-E)-2,7,11-trimethyl-12-oxo-2,4,6,8,10-tridecapentenal has been synthesised in 26percent overall yield in six steps from the readily available 3-methyl-2-penten-4-yn-1-ol and 2,7-dimethyl-2,4,6-octatrienedial.This C16-keto aldehyde was used in the first total synthesis of fully characterised (all-E)-sintaxanthin and optically active (all-E)-(3R)-3-hydroxysintaxanthin.The C16-keto aldehyde is a versatile building block for any C31-methyl ketone apocarotenoid.
