Carboncarbon bond formation by radical addition–fragmentation reactions of O-tert-alkyl enols and O-cyclopropylcarbinyl enols
摘要:
Terminal alkenes of the type H(2)C=C(OR(1))X, in which R(1) is a tertiary alkyl or a 1-cyclopropylethyl group and X=Ph, OSiMe(2)Bu', OEt or H, undergo radical-chain reactions with organic halides R(2)Hal to give carbonyl compounds R(2)CH(2)C(=O)X. (C) 2003 Elsevier Science Ltd. All rights reserved.
Carbacephem β-lactam antibiotics having chemical structures (I) and (II) are disclosed: including stereoisomers, pharmaceutically acceptable salts, esters and prodrugs thereof, wherein Ar2, R1, R2 and R6 are as defined herein. The compounds are useful for the treatment of bacterial infections, in particular those caused by methicillin-resistant Staphylococcus spp.
