Tests of a Piperidino Mask for the Protection of Functionalized Carbon Sites in Multistep Syntheses

Primary alkyl chlorides (R-Cl) are easily isolated in excellent yield after treatment of the appropriate N-alkylpiperidines (R-NC5H10) with α-chloroethyl chloroformate.The method is exemplified by the conversion of a variety of alkylpiperidines, including systems with other sensitive functionalities, to the respective chlorides in yields varying from 90 to 97percent.The potential significance of this process in drug congener preparation and in total synthesis is outlined.Similar fragmentations of N-sec-alkylpiperidines are described.
