134676-67-8, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. N-Boc-2-thiomorpholinecarboxylic Acid, cas is 134676-67-8,the Thiomorpholine compound, it is a common compound, a new synthetic route is introduced below.
Step 1 (+/-)-4-tert-butoxycarbonyl-N-(9-chloro-3,4-dihydro-2H-l,5-benzodioxepin- 7-ylmethyl)-N-isobutyl thiomorpholine-2-carboxamide: The mixture of N-(9-chloro-3,4- dihydro-2H- 1 ,5-benzodioxepin-7-ylmethyl)-2-methylpropan- 1 -amine (150 mg), thiomorpholine-2,4-dicarboxylic acid 4-tert-butyl ester (137 mg), l-ethyl-3-(3- dimethylaminopropyl)carbodiimide hydrochloride (138 mg), and dimethyl aminopyridine (92 mg) in dichloromethane (15 ml) was stirred at room temperature overnight. After the addition of water (10 ml), the mixture was extracted with 10 ml ethyl acetate three times. The organic layer was washed with saturated sodium bicarbonate, water and brine, dried over anhydrous sodium sulfate and concentrated under reduced pressure. The crude was purified by column chromatography on silica (20-33% ethyl acetate in hexane) to give the desired product as a resin: MS (m+l) = 499.4.
The chemical industry reduces the impact on the environment during synthesis,134676-67-8,N-Boc-2-thiomorpholinecarboxylic Acid,I believe this compound will play a more active role in future production and life.
