The two sulfur-containing amides entadamides A (93) and B (94) have been isolated from the seeds and entadimides A and C (95) from the leaves of Entada phaseoloides Merr. (valid name Entada rheedii Spreng.) (Legu-minosae) (99-101). The known isobutylamide alkaloid pellitorine (N-isobutyl-2 ,4 -decadienamide) is found in the aerial parts of Piper ri-besoides Wall. (102). Pellitorine has also been isolated from the fruits of P.

Complications arise when two esters of different acids are present or when acylation occurs on the aglycone. One must then rely on partial hydrolysis. The tactics are examplified hy the Entada saponins which contain C2 and Cjq acids (89). The acetate was selectively removed hy 0.025 % K2CO3 while both adds were removed by 1 % KOH. Comparison of C NMR spectra of the parent compound and of derivatives allowed determination of the points of acylation. The dicrotalic (3-hydroxy 3-methyl glutaric add) esters of the tubeistemosides and related compoimds (29-32) provide more complicated examples where the double anchoring of the diadd transforms a prochiral carbon atom into a center of chirality.
