Several 4-deoxy analogs of methyl β- D -galactopyranoside are oxidized by D -galactose oxidase. The rates associated with their various, axially attached 4-substituents follow the sequence OH>NH 2 >F⪢>Cl> H; these differences are attributed mainly

High-performance liquid chromatography has made possible the separation of furanosesquiterpenoids in Commiphora myrrh oil. Combined application of NMR, UV, and MS techniques have revealed that oil from C. myrrh gum resins contains isofuranogermacrene

Cordifene and cordifene 4β,15-oxide, extracted from the insect-antifeedant plant Erlangea cordifolia, have been examined by spectroscopic and X-ray techniques. Cordifene is shown by X-ray analysis (R 5.49%) as its 5-bromo-2-furoate (3c) to be the 8-

Methyl β- D - galacto -hexodialdo-1,5-pyranoside ( 2 ), produced by the action of D -galactose oxidase on methyl β- D -galactopyranoside, has been characterized in a dimeric form. Structural examination of the peracetate of this dimer by p.m.r. spe

In addition to cordifene (1) and cordifene 4β, 15-oxide (5), four new companion compounds cordifolia-54, -55, -P2, and -31 have been isolated from the insect-antifeedant plant Erlangea cordifolia. Cordifolia-54(2) is related to cordifene as the 2,3-
