- Synthesis of extremely simplified compounds possessing the key pharmacophore units of taxol, phenylisoserine and oxetane moieties
-
Straight chain compounds having a phenylisoserine unit and an oxetane ring at the α- and ω- position, respectively as extremely simplified analogues of taxol were prepared. None of these compounds showed promising tubulin inhibitory activity.

- The Synthesis of Octacidomycin
-
The total synthesis of octacidomycin (1), a novel oligocarboxylic acid antibiotic, and some shorter new model acids (19, 21, 24) is described.Key compounds in a series of fragment condensations of C19-, C5- and C2-units are α,α'-bis(bromopentyl)-substituted azealic- (6) and 3-(benzyloxypropyl)malonic esters (7).A six step synthesis yields bacteriostatically active octacidomycin (14=1). 14 and its octamethyl ester 15 are identical with the native products in all chemical and spectroscopic properties.Further combinations of fragments give tri-, tetra-, and pentacarboxylic acids.These demonstrate the flexibility of this widely variable synthetic method leading to new carboxylic acids and hydrocarbons.
