  Persistent splenomegaly in an adult female with homozygous sickle cell anemia

  摘要：

  Sickle cell anemia (SCA) is associated with repeated episodes of erythrostasis in the spleen, which lead to thrombosis and infarction of the spleen resulting in "autosplenectomy" which is usually complete by 8 years of age.We present a case of a 22-year-old female who presented with complaints of fever, bone pain and joint swelling. On examination she had pallor, icterus and moderate splenomegaly. Her hemoglobin was 7.5g/dl. Peripheral smear showed many sickled red cells. Slide test for sickling was positive with 2% sodium metabisulphite. Hemoglobin electrophoresis revealed a single band in the hemoglobin S, D, and G region. No band was seen in the HbA & HbA(2) region. HbF level was 0%. USG showed an enlarged spleen with few defined hypoechoeic lesion.We present this case because of rarity of association of homozygous SCA with splenomegaly in this age group, the confusion that echogenic lesions in spleen can create and to emphasize the risk of sequestration crises, which remains in such cases.

  an effective means to convert methyl 2‐(azidomethyl)‐3‐arylpropenoates and 2‐(azidomethyl)‐3‐arylacrylonitriles to the corresponding iminyl radicals via α‐hydrogen abstraction and subsequent extrusion of dinitrogen. Thus formed iminyl radicals then undergo intramolecular ortho attack on the aryl ring, affording methyl quinoline‐3‐carboxylates and quinoline‐3‐carbonitriles respectively.

  the directly dehydrative cross-coupling of allylic alcohols with terminal alkynes was developed. This calcium salt cocatalyst facilitates the oxidative addition of the palladium catalyst (1 mol %) to the C-OH bond. Then, the in situ-generated hydroxide ion deprotonates the terminal alkynes to promote the formation of the allylalkynylpalladium intermediate, liberating water as the only byproduct. This

  开发了一种高效的Pd / Ca催化体系，用于烯丙基醇与末端炔烃的直接脱水交叉偶联。该钙盐助催化剂促进了钯催化剂（1mol％）向C-OH键的氧化加成。然后，原位产生的氢氧根离子使末端炔烃去质子化，从而促进烯丙基炔基钯中间体的形成，释放出水作为唯一的副产物。密度泛函理论计算也支持这种提出的机制。由便宜的起始原料以10g规模制备抗癌剂。

• Baylis–Hillman reaction under solvent-free conditions — Remarkable rate acceleration and yield enhancement

  A simple and efficient method has been developed for remarkable rate acceleration and yield enhancement of the Baylis–Hillman reaction under solvent-free “neat conditions” and solvent-less isolation of products. Reaction of equimolar quantities of aldehyde and olefin in the presence of 20 mol% of DABCO under neat conditions affords the highest yield in most cases within the shortest reaction time, giving support to the mechanisms of proton transfer in protic and aprotic solvents. Solvent-free conditions are found to be especially fast, selective, and high yielding for aromatic aldehydes.

  为了在无溶剂的 "纯净条件 "下显著加快 Baylis-Hillman 反应的速率并提高产率，以及在无溶剂条件下分离产物，我们开发了一种简单而高效的方法。在 20 摩尔 DABCO 的存在下，等摩尔量的醛和烯烃在纯净条件下进行反应，在大多数情况下都能在最短的反应时间内获得最高的产率，为质子和非质子溶剂中的质子转移机制提供了支持。研究发现，在无溶剂条件下，芳香醛的反应尤其快速、选择性强且产率高。

  The utilization of ultrasound radiation in the Baylis–Hillman reaction with several aldehydes (aromatics and aliphatics) and different α,β-unsaturated reactants is described. For all aldehydes tested, the utilization of ultrasound sources augmented the reaction rate and the chemical yields. The use of ultrasound with two different catalysts (tri-n-butylphosphine and 1,4-diazabicyclo[2.2.2]octane [DABCO])
