Solid-phase synthesis of 3-hydroxymethyl isoxazoles via resin bound nitrile oxides
[3+2] Cycloaddition of alkynes to resin bound nitrile oxides gives after cleavage of 3,4,5trisubstitutedisoxazoles in acceptable yields and fair to good purity, depending on the alkyne substituents. The reaction has been automated on the ACT 496 synthesiser.

This disclosure relates to new phthalimide and isoindolinone derivatives and other PFKFB3 inhibitors for use in the treatment of diseases. The invention further relates to pharmaceutical compositions containing such PFKFB3 inhibitors, methods of preparation thereof, methods for their use as therapeutic agents, and methods of preparation of a medicament for use in therapy, as well as kits and other inventiions comprising such PFKFB3 inhibitors. These PFKFB3 inhibitors are useful for the treatment and prophylaxis of cancer, neurodegenerative diseases, autoimmune diseases, inflammatory disorders, multiple sclerosis, metabolic diseases, inhibition of angiogenesis and other diseases and conditions, where the modulation of PFKFB3 and/or PFKFB4 has beneficial effect as well as neuroprotection.
Certain cyclopentadienone monomers having polar moieties are useful in forming polyarylene resins having improved solubility in certain organic solvents and are useful in forming polyarylene resin layers in electronics applications.

Both esters are essentially linear acetylenes with m-0 bond angles of 174.7' and 177.6', respectively. The m-0 acetylenimxygen bond length is 1.331 (4) A in 4 and 1.329 (4) A in 5, significantly shorter than the analogous bond length in the corresponding saturated alkyl or vinyl esters. There is a concomitant increase in the S-0 or 0-C(=O) bond lengths from saturated to vinyl (enol) to alkynyl esters
测定了甲苯磺酸丙炔酯 4 和苯甲酸乙炔酯 5 的单晶 X 射线结构。两种酯基本上都是线性乙炔,m-0 键角分别为 174.7' 和 177.6'。m-0 炔氧键长在 4 中为 1.331 (4) A,在 5 中为 1.329 (4) A,明显短于相应饱和烷基酯或乙烯基酯中的类似键长。从饱和到乙烯基(烯醇)再到炔基酯,S-0 或 0-C(=O) 键长随之增加。几个较小模型系统的从头算分子轨道计算 (6-31G*) 与 X 射线几何结构非常吻合,包括作为 R 函数发生的变化(R = 炔基、乙烯基、烷基)。HCsOS02R, 7, 更喜欢 gauche 构象(LHSCO = 70° R = H 和 76' R = Me)。围绕 S-0 键旋转的障碍在 7 中为 2.7 kcal mol-',R = H,在 7 中为 4.8 kcal mol-',R = Me (6-31G*)。已经计算了这些酯的
