Abstract
Several methods for the conversion of virescenol B tosylate (1c) into the oxetane (2) are described. On exposure to triphenyldi-iodophosphorane, (2) was transformed into the iodohydrin (1g), whose lithium–ammonia reduction led to the known isopimara-7,15-dien-19-ol (1b).File in questo prodotto:
