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′
通过按照方案C 19 + C 2 + C 19= C 40构筑C 40骨架,合成了3,4; 3',4'-双氢-β-胡萝卜素和3,4-单氢-β-胡萝卜素。的对称3,4-合成; 3',4'-bisdehydro-β胡萝卜素是基于使用的脱氢-β-C的两个单元19 -醛。非对称3,4- monodehydro-β胡萝卜素从一个单元中的每个的脱氢-β-C形成19 -醛和β-C 19 -醛。3,4; 3',4'-双去氢-β-胡萝卜素比3,4-单去氢-β-胡萝卜素形成更亮的红色溶液。在生长试验中,前者显示出38%的β-胡萝卜素活性,而后者显示了75%的β-胡萝卜素活性。
