Notes:
3,4;3′,4′-Bisdehydro-β-carotene and 3,4-monodehydro-β-carotene are synthesized by building up the C40skeleton following the scheme C19 + C2 + C19 = C40. The synthesis of the symmetrical 3,4;3′,4′-bisdehydro-β-carotene is based on the use of two units of dehydro-β-C19-aldehyde. The asymmetrical 3,4-monodehydro-β-carotene is formed from one unit each of dehydro-β-C19-aldehyde and β-C19-aldehyde. 3,4;3′,4′-Bisdehydro-β-carotene forms brighter red solutions than 3,4-monodehydro-β-carotene. In the growth test the former showed 38% and the latter 75% of the activity of β-carotene.
