3382-18-1, Name is 6,7-Dimethoxy-3,4-dihydroisoquinoline, belongs to isoquinoline compound, is a common compound. Formula: C11H13NO2In an article, once mentioned the new application about 3382-18-1.
The enantiospecific synthesis of (S)-(-)-8-oxoxylopinine 1 was performed using a lateral metallation strategy, in which (S)-alaninol or (S)-phenylalaninol was applied as chiral auxiliary and building block. (4S)-3-(4,5-Dimethoxy-2-methylbenzoyl)-2,2,4-trimethyl-1,3-oxazolidine 12 was synthesized starting from veratraldehyde 13. The addition reaction of benzylic anion generated in situ from chiral amide 12 into 6,7,-dimethoxy-3,4-dihydroisoquinoline 7a proceeded with simultaneous cyclization leading to the protoberberine alkaloid with high enantioselectivity.
