Six-membered Systems with One Heteroatom

In 1998, Khmelnitsky and coworkers examined microwave-assisted parallel Hantzsch pyridine synthesis [59]. They demonstrated the benefits of microwave ir- 

4-02NCeH4, 4-CIC6H4,2-naphthyl, 4- and 3-tolyl, yields from 83 to 98% 

This new one-pot Bohlmann-Rahtz procedure, conducted at 170 °C in a self-tunable microwave synthesizer, gives superior yields to similar experiments conducted using conductive-heating techniques in a sealed tube, and can be performed in the presence of a Bronsted or Lewis acid catalyst. 

A new type of N-hydroxylacridinedione derivative was recently obtained in excel- 

In 2004, Walla and Kappe described a more straightforward means of access to arylzinc halides - microwave-accelerated Rieke Zn insertion into aryl halides [67].
