    • 8 200 mol % of methyl chloroformate gave a 73% yield of lactone 19. Monitoring the reaction by TLC showed that lactone formation was concomitant with chloro ester formation. Lactonization of chloro ester 15 may be facilitated by lithium chloride present in the reaction mixture or may be solely a thermal process (attempted GC purification of 15 at 180 °C yielded lactone 19). Similar results have been reported by
