Rs. Atkinson et al., AZIRIDINATION OF ALKENES WITH 3-ACETOXYAMINOQUINAZOLINONES IN THE PRESENCE OF HEXAMETHYLDISILAZANE, Journal of the Chemical Society. Perkin transactions. I, (3), 1998, pp. 583-589
Yields of aziridines from reaction of some alkenes, including alpha,be
ta-unsaturated esters, with 3-acetoxyamino-2-isopropylquinazolinone 6
(Q(3)NHOAc) are greatly increased in the presence of hexamethyldisilaz
ane (HMDS). A mono-aziridination product of naphthalene is obtained on
ly in the presence of HMDS. It is concluded that the enhanced yields i
n these aziridinations are the result of scavenging of acetic acid by
HMDS, thus prolonging the lifetime of the aziridinating agent Q(3)NHOA
