Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 92-39-7, Name is 2-Chloro-10H-phenothiazine, molecular formula is , belongs to thiazines compound. In a document, author is Sharma, Rashmi, Safety of 2-Chloro-10H-phenothiazine.
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.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 92-39-7, in my other articles.
