摘要：
Unlike unsaturated compounds containing alkyl groups at the double bond, low-temperature chlorination of betulin diacetate with tert-butyl hypochlorite involves mainly replacement of hydrogen in the vinylic position to give Z- and E-isomeric chlorides and a small amount of the allylic isomer, the latter resulting from elimination of hydrogen from the (CH3)-H-30 group.
