As part of our program concerning the synthetic potential of 1-chloroalkyl carbonochloridatesm, we were interested in the development of 1-chloroalkyl carbollates us reagents for organic synthesis. These carbonates are known to react with nueleophiles to effect chlorine displacement. and this property has been widely used in the modification of antibio-tics '. We have already described the use of l. 2.2, 2-tctrachl0-roethyl 1-butyl ...
