derivatives substituted in the 4-position by either a 2- or 3-substituted thiophene ring have been synthesised. Simple electrophilic substitution reactions of these systems take place as expected in the α-position of the thiophene ring. Metalation reactions are more complex and take place at the benzylic 4-position of the tetrahydroisoquinoline nucleus in the case of the 2-substituted thiophene derivatives
已经合成了在4-位被2-或3-取代的噻吩环取代的四氢异喹啉衍生物。这些系统的简单亲电取代反应如预期的那样在噻吩环的α位发生。金属化反应更复杂,并且在发生2-取代的噻吩衍生物的情况下,发生在四氢异喹啉核的苄基4-位,或者在噻吩α-位或苄基4-位发生,具体取决于攻击亲电试剂的性质。对于3-取代的噻吩系统。
