Electric Literature of 19771-63-2, Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. Electric Literature of 19771-63-2, Name is (R)-2-Oxothiazolidine-4-carboxylic acid,introducing its new discovery.
INTERMEDIATE FOR BIOTIN AND PROCESS FOR PRODUCING THE SAME
The present invention is to provide a process for preparing a synthetic intermediate of biotin which is industrially advantageous, and discloses a process for preparing a compound represented by the formula (I) :???wherein R1 and R2 may be the same or different from each other, and each represents hydrogen atom, a benzyl group which may have a substituent(s) on the benzene ring, a benzhydryl group which may have a substituent(s) on the benzen ring, or a trityl group which may have a substituent(s) on the benzene ring, R3 represents cyano group, carboxyl group, an alkoxycarbonyl group, an alkylthiocarbonyl group, or a carbamoyl group which may have a substituent, or a salt thereof which comprises subjecting a compound represented by the formula (II-a) :???wherein the symbols have the same meanings as defined above, or a salt thereof to ring transformation.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 19771-63-2, and how the biochemistry of the body works.Electric Literature of 19771-63-2
