Boronic acids synthesis

Phenyl boronic acid synthesis (Clariant/Frankfurt) [10]... 

Temperature profile of the phenyl boronic acid synthesis along the major steps of the process flow scheme. The difference in the temperatures of the conventional batch and the microreactor processes stand for the reduction in energy consumption and respective heat-transfer equipment when using the latter [10]... 

Starting from substituted allyl bis-(2,4-dimethyl-3-pentyl)-L-tartrate boronic acid, synthesis of a,/l-disubstituted tetrahydrofurans (134, n = 1) or tetrahydropyrans (134, n = 2) can be accomplished with high enantioselectivity (Scheme 3-46).79...
