Method of synthesis of 3-exomethylenecephame sulfoxide ester |
| abstract |
FIELD: organic chemistry. SUBSTANCE: chlorosulfinylazetidine of the general formula (1), where A - amino-protecting group and R - carboxyl-protecting group, is cyclized in dry inert organic solvent in the presence of catalyst (kind of Lewis acid) at temperature and for time that are sufficient for synthesis of compound of the general formula (2). Process is carried out in the presence of nitrocompound taken from a group containing nitro-C 1 -C 6 -alkanes and nitrobenzene. EFFECT: improved method of synthesis. 35 cl, 2 dwg |
