Efficient approaches to the central amino-epoxycyclohexenone core of t
he manumycin family of antibiotics are described, The use of this meth
odology to prepare the antitumour antibiotic LL-C10037 alpha and its e
pimer, both in racemic form, and a number of analogues of manumycin, a
lisamycin and asukamycin, lacking the C-4 substituent, ate then outlin
