摘要:
An efficient one-pot synthesis of novel beta-amino acid derivatives containing a thiadiazole moiety was developed using a chiral squaramide cinchona alkaloid as organocatalyst. The reactions afforded chiral beta-amino acid derivatives in moderate yields and with moderate to excellent enantioselectivities. The present study demonstrated for the first time the use of a Mannich reaction catalyzed by a chiral bifunctional organocatalyst for the one-pot synthesis of novel beta-amino acid derivatives bearing a 1,3,4-thiadiazole moiety on nitrogen.
