gamma- and delta -Hydroxyamides can be prepared in high yields by heating a lactone with ammonia in a pressure tube. The ammonia can be removed by controlled evaporation with ice/acetone cooling.

An enzyme was expressed in Escherichia coli from a cloned amidase gene. When characterized, it was more enantioselective than commercial amidases. Three pheromones were made using this biotransformation chemistry. (C) 2004 Elsevier Ltd. All rights reserved.
Novel autophagy modulators: Design and synthesis of (+)-epogymnolactam analogues and structure-activity relationship
from a culture of Gymnopus sp. in our laboratory. To determine structure-activity relationships among (+)-epogymnolactam analogues comparing with cerulenin (2), we synthesized 5 analogues including (−)-epogymnolactam (3) having each different functional group, and 3 analogues with different side-chain lengths. Five analogues, 3, 4, 5, 6, and 7 did not significantly increase the ratio of LC3-II to LC3-I
