28276689-1	2017	An improved route for the synthesis of the KLMN fragment of gymnocin-A was developed through the oxiranyl anion coupling of the FGH fragment with a chiral C3 epoxy sulfone, followed by 6-endo cyclization.	oxiranyl anion	97-111	esterase D	Homo sapiens	128-131	
26521846-2	2015	The synthesis features three iterations of an oxiranyl anion strategy, involving base-mediated cycloetherification, ring expansion, and reductive etherification, for the construction of the FGH fragment and for its coupling with the ABC and KLMN fragments.	oxiranyl anion	46-60	esterase D	Homo sapiens	190-193
