Chemical research careers are more diverse than they might first appear, as there are many different reasons to conduct research and many possible environments. 92-39-7, Name is 2-Chloro-10H-phenothiazine, belongs to thiazines compound, is a common compound. In a pantent, author is Sharma, Rashmi, once mentioned the new application about 92-39-7, Category: thiazines.
A Facile and Chemoselective Synthesis of Novel Pyrimido[5,4-b][1,4]thiazines by exo-dig Iodocyclization Reactions
The present manuscript involves the synthesis of 5-prop-2-ynylsulfanyl-pyrimidin-4-ones 3a-i by [4+2] cycloaddition reactions of 1,3-diazabuta-1,3-dienes 1a-i with prop-2-ynyl-sulfanyl ketene 2. These 5-prop-2-ynylsulfanyl-pyrimidin-4-ones 3a-i were explored in iodocyclization for the synthesis of novel pyrimido[5,4-b][1,4]thiazines 4a-i in excellent yields. The iodocyclizations followed exo-dig ring-closure cyclizations to yield 6-6 bicyclic fused pyrimidinones, while corresponding endo-dig ring-closure iodoamination was not observed.
I am very proud of our efforts over the past few months and hope to 92-39-7 help many people in the next few years. Category: thiazines.
