Rearrangements of 1,6,7-Trisubstituted 2-Methyl-1,2,3,4-tetrahydroisoquinolinium 2-Methylides
Chemical behavior of 1,6,7-trisubstituted 2-methy-1,2,3,4-tetrahydroisoquinolinium 2-methylides 4 was investigated in fluoride-ion induced desilation reaction of 1,6,7-trisubstituted 2-methyl-2-(trimethylsilyl)methyl-1,2,3,4-tetrahydroisoquinolinium iodides 3.The 1-nonsubstituted (4a,b) and 1-alkyl-substituted ylides (4c,d) gave mixtures of five products (7-11), but the 1-phenyl-substituted analogues (4e,f) yielded (E)- and (Z)-2,3-disubstituted 5-benzylidene-1,3-cyclohexadiene-6-spiro-3′-1′-methylpyrrolidines (E)-5 and (Z)-5 and 7,8-disubstituted 3-methyl-1-phenyl-2,3,4,5-tetrahydro-1H-3-benzazepines 6.The mechanisms of the rearrangement are discussed.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 1745-07-9
