Research speed reading in 2021. An article , which mentions Reference of 3340-78-1, molecular formula is C15H15N. The compound – 2-Phenyl-1,2,3,4-tetrahydroisoquinoline played an important role in people’s production and life., Reference of 3340-78-1
N-Alkyl- and N-arylsubstituted 1,2,3,4-tetrahydroisochinolin-1-phosphonates 1 have been synthesized from the corresponding 3,4-dihydroisochinoliniumbromides 7 and triethylphosphite.The N-unsubstituted 1,2,3,4-tetrahydroisochinolin-1-phosphonate 10 is available starting from the 1,2,3,4-tetrahydroisochinolin-1-phosphonic acid by esterification with triethylformate and splitting off the formyl group of the primarily formed N-formyl derivative 14. – N-Quarternated tetrahydroisochinolines 19 and the 1-phosphorylated derivatives 17, respectively react with triethylphosphite in an unexpected way by dealkylation and not by splitting off the isochinolinring. – By Horner-synthesis with 1 the 1-aralkylidene-isochinolines 23 are available in moderate yields.
