| titleOfInvention | Stereoselective production method of 4-BMA using chiral auxiliary |
| abstract | The present invention provides (3R, 4S) -3-[[[R] -1′-t-butyldimethylsilyloxy] ethyl] -4, an important intermediate for the synthesis of carbapenem and penem antibiotics. The present invention relates to a process for producing [(R) -1 ″ -carboxyethyl] -2-azetidinone [4-BMA: Formula (6)]. In particular, the present invention relates to a process for producing 4-BMA with high yield and high selectivity under industrially mild conditions after synthesizing a chiral auxiliary from inexpensive L-valinol. |
