摘要:苯基硼酸酯的磺酰氯可通过选择性锂化溴代n-甲基二乙醇胺苯基硼酸盐,反应生成锂亚磺酰苯基硼酸盐中间体,再通过与n-氯代琥珀酰亚胺氧化,得到目标磺酰氯.这些新的试剂在制备苯基硼酸的磺酰胺以及其他化合物中非常有用,这些化合物可用于钯(0)催化的交叉偶联反应.此外,它们还具有作为生理pka条件下碳水化合物结合剂的潜力.

摘要:The present invention relates to halo sulfonyl aryl boronates of the general formula (I): n n wherein Arylene designates a carbocyclic or heterocyclic, aromatic ring system comprising 1-3 rings; R 1 , R 2 and R 3 are, independently, hydrogen, C 1-6 alkyl, C 1-6 alkoxy, halogen, nitro, cyano or phenyl; X is fluoro, chloro or bromo; and Y is a boroxine moiety attached via a bond from Arylene to one of the boron atoms of a boroxine ring which ring has a group of the formula -Arylene(R 1 )(R 2 )(R 3 )SO 2 X, wherein Arylene, R 1 , R 2 , R 3 and X are as defined above, at each of the other two boron atoms of the boroxine ring, or Y is a boronic acid group or a boronic ester group. The invention also relates to the preparation of the compounds of formula (I) and to their use in organic synthesis.
