Name is 4-(tert-Butoxycarbonyl)thiomorpholine-3-carboxylic acid, as a common heterocyclic compound, it belongs to Thiomorpholine compound, and cas is 128453-98-5, its synthesis route is as follows.
To a solution of N-Boc thiomorpholine carboxylic acid (1.36 g, 5.51 mmol) in dichloromethane (13.6 ml) were added under N2, at r.t., TBTU (1.95 g, 6.06 mmol) and DIPEA (1.92 ml, 11.02 mmol) and the solution was stirred for 30 mins. To a suspension of L-serine methyl ester hydrochloride (1.71 g, 11.02 mmol) in dichloromethane (13.6 ml) was added DIPEA (1.92 ml, 11.02 mmol) and the resulting solution was stirred for 30 mins. Then the solution containing the serine free base was added to the reaction mixture and it was left stirring for 16 hrs. Water was added to the reaction mixture and the aqueous layer was extracted with dichloromethane (x3) and the combined organic phases were dried (Na2SO4) and evaporated to dryness. The crude title compound (3.87 g) was used in the next step without further purification. UPLC/MS: m/z= 371 (M+Na); 349 (M+1 ); 293 (M-fBu); 249 (M-BOC+1 ) (at) t=0.59 min
128453-98-5, In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles.,128453-98-5 ,4-(tert-Butoxycarbonyl)thiomorpholine-3-carboxylic acid, other downstream synthetic routes, hurry up and to see
