In 2019,Organic Letters included an article by Zeng, Rong; Shan, Changyu; Liu, Ming; Jiang, Kun; Ye, Ying; Liu, Tian-Yu; Chen, Ying-Chun. Category: bromides-buliding-blocks. The article was titled 《[4 + 1 + 1] Annulations of α-Bromo Carbonyls and 1-Azadienes toward Fused Benzoazaheterocycles》. The information in the text is summarized as follows:
An unexpected [4 + 1 + 1] annulation between α-bromo carbonyls and 1-azadienes, derived from 2-methylenebenzofuran-3(2H)-ones or 2-methylenebenzo[b]thiophene-3(2H)-ones, was observed in the presence of DABCO and Cs2CO3. These reactions stand in contrast to the common [4 + 1] cyclization reactions of azadienes with the related sulfonium ylides. A range of fused benzofuro[3,2-b]pyridines and benzo[4,5]thieno[3,2-b]pyridines were efficiently constructed in fair to excellent yields. In the part of experimental materials, we found many familiar compounds, such as Benzyl 2-bromoacetate(cas: 5437-45-6Category: bromides-buliding-blocks)
Benzyl 2-bromoacetate(cas: 5437-45-6) belongs to benzyl acetate. Benzyl acetate is a synthetic chemical produced for industry from benzyl alcohol and acetic acid, but is also naturally present in the essential oils of many plants, including jasmine and ylang ylang.Category: bromides-buliding-blocks
