  • Does the Photochemical Conversion of Colchicine into Lumicolchicines Involve Triplet Transients? A Solvent Dependence Study¶

    transfer to COL from triplet acetone produced by either isobutanal/horseradish peroxidase system or tetramethyldioxetane thermolysis failed to provoke photoreaction of COL. Our data argue against the intermediacy of a COL triplet state in the photoisomerization and stress on the role of specific solvent–solute interactions in determining the partitioning of excited singlet state into the β- and γ-isomer
    摘要 β-和γ-发光秋水仙碱是秋水仙碱(COL)生物碱的托酚酮环环化异构化形成的光产物。通过研究溶剂极性对 lumicolchicine 光异构体比率的影响,研究了光转化的机制,建议涉及三重态。通过激光闪光光解检测到的三重 COL 被氧气淬灭,但不被反式二苯乙烯或 1-甲基萘。COL 转化的量子产率和光产物比率都不会因氧的存在而改变。同样,能量从异丁醛/辣根过氧化物酶系统或四甲基二氧杂环丁烷热解产生的三线态丙酮转移到 COL 未能激发 COL 的光反应。
  • Photochemical Isomerization of Colchicine and Thiocolchicine

    The photochemical reactivity of colchicine and thiocolchicine is described. Although the irradiation of colchicine gave a well-known transposition reaction to beta- and gamma-lumicolchicines, thiocolchicine did not react. Femtosecond transient spectroscopy of colchicine showed a strong band with maximum at 510 nm appearing at tau = 0. It disappeared within few hundred femtoseconds, leaving a broad structureless band with a maximum around 470 urn. A second band is observed around 410 nm. The analysis in time showed that the 510-nm component appeared instantaneously and decayed following a biexponential low with time constants of 300 +/- 100 fs and 40 ps. The kinetics at 420 nm has a measurable rise lime of 300 +/- 150 fs. Quantum mechanical calculations on colchicine showed that this absorption is due to a S-1 --> S-11 transition. In thiocolchicine, the instantaneous formation of a structure with maxima out of the investigated spectral region was observed. A strong absorption around 650 nm indicated the presence of a band with a maximum at longer wavelengths (> 700 nm) and a peak around 380 nm, which partially coincides with the ground-state absorption and therefore strongly affected absorption around 650 nm and its rapid (similar to500 fs) decay by its bleaching. The instantaneous formation of an absorption was observed. At shorter wavelengths (400 nm), the t decay was fitted with a biexponential curve with the first time constant of about 80 ps. The second part of,the decay had a very long tail up to 500 ps. Transient spectroscopy and configuration interaction calculations are in agreement with a mechanism involving a disrotatory cyclization of colchicine in its first excited singlet state. The lack of reactivity observed in thiocolchicine was explained by considering the presence of efficient ISC to the triplet state.
