• Convenient Synthesis of .ALPHA.-Trifluoromethylated Acyloins from .ALPHA.-Hydroxy or .ALPHA.-Amino Acids.

  acyloins (2 and 6) have been prepared from alpha-hydroxy acids (1), N-acylprolines (5) or N-acyl-N-alkyl alpha-amino acids (8) by novel transformation reactions with trifluoroacetic anhydride (TFAA) in the presence of pyridine. The former reaction of 1 could proceed through mesoionic 1,3-dioxolium-4-olates, whereas the latter two reactions of alpha-amino acids (5 and 8) could involve mesoionic 1,3-oxazolium-5-olates

  α-三氟甲基化酰基辅酶（2和6）是由α-羟基酸（1），N-酰基脯氨酸（5）或N-酰基-N-烷基α-氨基酸（8）与三氟乙酸酐（ TFAA）在吡啶存在下。前者1的反应可以通过1,3-二氧恶唑鎓4-olates进行，而后两个α-氨基酸（5和8）的反应可能涉及1,3-二恶唑鎓5-olates。1与TFAA的反应在实际应用中显示出更大的潜力，这是因为起始材料易于使用且易于操作。

  Several semisynthetic maytansinoids that differ in the structure of the acyl group at the C3 position were prepared by acylation of maytansinol (3) using appropriate carboxylic acids or their active derivatives, and the effects of the compounds on the growth of Tetrahymena pyriformis and the survival of tumor-bearing mice were determined. Among these analogs, the C3 esters having a straight chain aliphatic acyl (11, 12), cycloalkanecarbonyl (18-20) or phenylacetyl group (22), and those having a 2-(N-acetyl-N-methyl) aminohexanoyl (7) or (2-(N-acetyl-N-methyl) aminophenylpropionyl group (8), strongly inhibited the growth of T. pyriformis and exhibited potent activity against B16 melanoma in mice. The potencies were similar to those of maytansine and ansamitocin P-3. The most striking result was the finding that the phenylglycinate (31) was superior to maytansine in terms of its broader effective dose range against ip B16 melanoma and P388 leukemia in mice ; however, higher doses of the phenylglycinate were required.

  几种半合成的美坦素类药物，其C3位置的酰基结构不同，是通过使用适当的羧酸或其活性衍生物对美坦醇（3）进行酰化而制备的。研究了这些化合物对梨形兽原虫（Tetrahymena pyriformis）生长和肿瘤-bearing小鼠生存的影响。在这些类似物中，具有直链脂肪酸酰基（11, 12）、环烷酸酰基（18-20）或苯乙酰基（22）的C3酯，以及具有2-(N-乙酰-N-甲基)氨基己酸酰基（7）或2-(N-乙酰-N-甲基)氨基苯丙酸酰基（8）的化合物，极大地抑制了T. pyriformis的生长，并对小鼠的B16黑色素瘤表现出强烈的活性。这些化合物的效力与美坦素和安萨米托新P-3相似。最引人注目的结果是发现苯甘氨酸酯（31）在对小鼠腹腔B16黑色素瘤和P388白血病的有效剂量范围上优于美坦素；然而，需要更高剂量的苯甘氨酸酯。

  A new fragmentation reaction of secondary α-amino acids with trifluoroacetic anhydride under Dakin-West reaction conditions proceeds through oxazolium salt intermediates followed by ring cleavage to form α-trifluoromethylated acyloins in good yields.

  The 1,3-dipolar cycloaddition of several substituted Münchnones with methyl α-cyanocinnamate and α-cyanocinnamonitrile leads to 2-pyrrolines which may be aromatized to pyrroles. This study shows the influence of steric factors on the regioselectivity of the reaction which is “a priori” difficult to predict.

  用α-氰基肉桂酸甲酯和α-氰基肉桂腈甲基取代数个取代的慕尼黑酯的1，3-偶极环加成反应会生成2-吡咯啉，可将其芳香化为吡咯。这项研究表明，空间因素对反应的区域选择性的影响是“先验”很难预测的。
• Stereodefined ring contraction-rearrangement of thiocoumarins to new fused benzo[b]thiophene derivatives

  Mesoionic 1,3-oxazolium-5-olates (münchnones) react with thiocoumarins having an electron-withdrawing group at the 3-position to afford stereodefined fused polycyclic thienopyrroles. The reaction sequence seems to be triggered by a regiospecific dipolar cycloaddition followed by ring opening of the initial 1:1 cycloadduct and intramolecular rearrangement with an unusual ring contraction.

  中离子1,3-恶唑鎓5-酸酯（münchnones）与在3-位具有吸电子基团的硫香豆素反应，得到立体定义的稠合多环噻吩并吡咯。反应顺序似乎是由区域特异性偶极环加成反应引发的，随后是最初的1：1环加合物的开环，以及分子内的重排以及异常的环收缩。
