The cycloaddition of diazoalkanes, diazoesters and diazoketones to 2(5H)-furanones followed by thermal decomposition of the respective adducts is shown to provide a general method for the preparation of a variety of alkylated 2(5H)-furanones. Reducti

Tenuifolin (V), a prosapogenin isolated from the roots of P. tenuifolia and P. senega , has been shown to be 2β,27-dihydroxy-23-carboxyoleanolic acid 3β-O-glucoside, on the basis of physical data of tenuifolin and several of its degradation product

A detailed study of the basic components of the roots of Aconitum heterophyllum has led to the isolation of seven new diterpene alkaloids. The weak base fraction yielded besides heteratisine, three more alkaloids designated as heterophyllisine, heter

Publisher Summary This chapter discusses C19-diterpene alkaloids. The structures of the more complicated diterpene alkaloids may be subdivided into two general types that are closely related. The first is the lycoctonine-type that is based on the par

A study of the NMR spectra of 44 diterpene alkaloids and derivatives is reported. A comparison of the NMR data for the C(4) Me group in a series of derivatives of atisine and veatchine provides support for the previous proposal regarding the conforma

Publisher Summary This chapter introduces diterpene alkaloids. The diterpene alkaloids are derived from tetracyclic or pentacyclic diterpenes in which carbon atoms 19 and 20 are linked with the nitrogen of a molecule of β-aminoethanol, methylamine,
