SIX DITERPENES FROM VELLOZIA COMPACTA
Pinto, Angelo C.,Borges, Cristina
, p. 2011 - 2016 (1983)
Vellozia compacta contains six new diterpenes of the pimarane type.Their structures were deduced on the basis of spectral data and chemical modification.Key Word Index-Vellozia compacta; Vellozizceae; Monocotyledoneae; pimarane-type diterpenes; structure elucidation.
Synthesis of enantiomeric gibberellin analogs from natural isopimarenes
Pinto,De Epifanio,Camargo
, p. 5039 - 5046 (2007/10/02)
The natural isopimarenes 2-5, isolated from Velloziaceae species, with known absolute stereochemistry, were submitted to chemical transformations and afforded the tetracyclic lactones 10 and 11 with the gibberellane skeleton of the normal series. The 15-oxa-gibberellanes obtained are enantiomeric analogs of the natural gibberellins and this represents the first synthesis of this type of compounds.
OXIDATIVE CLEAVAGE OF 1,2-GLYCOLS AND α-HYDROXY KETONES WITH THE JONES REAGENT
Epifanio, Rosangela de A.,Camargo, Wilson,Pinto, Angelo C.
, p. 6403 - 6406 (2007/10/02)
The oxidative cleavage of secondary-tertiary 1,2-glycols and α-hydroxy ketones with the Jones reagent proved to be a particularly useful synthetic procedure to form the corresponding ketoacids in excellent yields.
