摘要：
1-[alpha-(Benzotriazol-1-yl)alkyl]-2-napthols and 2-[(benzotriazol-1-yl)-methyl]phenols have been shown to lose a molecule of benzotriazole to generate o-quinone methides, which can be trapped with electron-rich olefins (ethyl vinyl ether, 1-vinyl-2-pyrrolidinone) to afford chroman derivatives, i.e. 2,3-dihydro-1H-naphtho[2,1-b]pyrans and 3,4-dihydro-2H-1-benzopyrans, respectively.
