Use | (R)-2-(O-methyl) benzene-CBS-oxazole-boridine can be used as a synthetic intermediate in pharmaceutical and chemical industry. If inhaling (R)-2-(O-methyl) benzene-CBS-oxazolboridine, move the patient to fresh air; If skin contact, remove contaminated clothing, thoroughly rinse the skin with soap water and water, and seek medical advice if you feel uncomfortable. When the protonation reaction is carried out between chiral oxaboridine and trifluoromethanesulfonimide, chiral Lewis acid can be generated, this acid has proven to be very suitable for enantioselective Diels-Alder reactions. 1,2 |
