A novel, concise, and efficient enantioselective synthesis of (S)-preclamol (87% ee, 51% total yield) has been developed. The key steps of this synthetic approach included cobalt-catalyzed asym. catalytic cross-coupling of α-bromo ester with arylzinc and the reduction of chiral ester to diol with a tertiary carbon atom. Moreover, it was demonstrated that our enantioselective Negishi cross-coupling was a powerful tool to construct stereogenic benzylmethyl center in chiral drugs on a gram scale. The experimental process involved the reaction of 1-Bromo-3-methoxybenzene(cas: 2398-37-0Recommanded Product: 2398-37-0)
1-Bromo-3-methoxybenzene(cas: 2398-37-0) can be used in chemical reaction as intermediates to obtain target materials such as dyes, pharmaceuticals, perfumes, photoinitiators and agrochemicals.Recommanded Product: 2398-37-0
