Houminer, Yoram; Sanders, Edward B. published an article in 1980, the title of the article was The reaction of alkylpyrazine anions with some electrophiles. Synthesis of 1,2-bis(2-pyrazyl)ethanes.Application In Synthesis of 5,6,7,8-Tetrahydroquinoxaline And the article contains the following content:
The coupling of pyrazines I (R-R2 = Me, H; R = R1 = H, R2 = Me; R = Me, R1 = R2 = H) using LiN(CHMe)2(LDA)-iodine gave II (31-43%). The treatment of I (R-R2 = Me) with LDA and O gave 21% I (R = CH2OH, R1 = R2 = Me), which was coupled with I (R = Me, R1 = R2 = H) to yield 49% III. (±)- And meso-IV were prepared by the treatment of 5,6,7,8-tetrahydroquinoxaline with LDA and O. The experimental process involved the reaction of 5,6,7,8-Tetrahydroquinoxaline(cas: 34413-35-9).Application In Synthesis of 5,6,7,8-Tetrahydroquinoxaline
