31. Five additional research groups have reported successful total syntheses of paclitaxel : convergent syntheses . 32. There are many laboratory syntheses of uracil available. 33. Some other explosive syntheses do not require oleum. 34. Some researchers prefer Boc SPPS for complex syntheses . 35. Because of the ease of these syntheses , many analogues of acetylacetonates are known. 36. It studies the physical and chemical properties, syntheses and structures of coordination compounds. 37. He was also an editor and contributor for " Organic Syntheses ". 38. Other syntheses have also been developed, such as oxidizing tetrahydrothiophene with hydrogen peroxide. 39. It is used in some chemical syntheses , as a precursor or a catalyst. 40. It is also more sterically hindered, though it is still useful for syntheses .
