## Carbazolone 5 has been converted in eleven steps into alkaloid analog Z (R = Me) (13 46 overall yield). In the preceding paper l, we proposed a new approach to pentacyclic Aspidosperma alkaloids [(e.g. (-)-aspidospermldine, 1, R = Et], based on the disconnection [l -+ 2 -+ 31, in which carbazol

A new stereospecific synthesis of lysophosphatidylcholines is reported. The sequence relies on orthogonal protection of hydroxyl groups derived from glyceric acid, using fluorenylmethylcarbonate versus tetrahydropyranyl ether functions, that allow regiospecific introduction of substituents to obtain
