Zh., (5), 32-5 (Russian) 1991.Several substances with their cas registry numbers 6451-86-1 and 621-59-0 may be metioned in this study. CODEN: UZKZAC. ISSN: 0042-1707. DOCUMENT TYPE: Journal CA Section: 27 (Heterocyclic Compounds (One Hetero Atom)) A possible intramol. ipso-substitution in the Bischler-Napieralski reaction of N-(3-benzyloxy-6-bromo-4-methoxyphenethyl)-3,4-dimethoxyphenylacet amide which results in cyclization at C atom contg. bromine was demonstrated. Thus, treating amide I, prepd. in 3 steps from 3-hydroxy-4-methylbenzaldehyde, with POCl3 in abs. benzene gave 59.6% isoquinoline deriv. II. .

A new synthesis of phthalides by internal trapping in ortho-lithiated carbamates derived from benzylic alcohols: A new synthesis of phthalides by internal trapping in ortho-lithiated carbamates derived from benzylic alcohols. Paleo, M. Rita; Lamas, Carlos; Castedo, Luis; Dominguez, Domingo (Fac. Quim., Univ. Santiago, Santiago de Compostela 15706, Spain). J. Org. Chem., 57(7), 2029-33 (English) 1992.Several substances with their cas registry numbers 6451-86-1 and 139016-06-1 may be metioned in this study. CODEN: JOCEAH. ISSN: 0022-3263. DOCUMENT TYPE: Journal CA Section: 27 (Heterocyclic Compounds (One Hetero Atom)) Section cross-reference(s): 31 The addn. of tert-BuLi to a low-temp. THF soln. of o-bromo carbamates I (R = H, OMe, O2CNMe2; R1 = OMe, OCH2Ph; R2 = OMe, OCH2Ph, H; R3 = Br) leads to ortho-lithiated intermediates I (R3 = Li), in which internal trapping by the electrophile on the side chain then takes place. This novel Parham-type anionic cyclization procedure affords the variously substituted phthalides II in high yields and can also be used for the prepn. of lactones III (R4 = H, Br; R5 = H, Br, OMe; R6 = H, OMe), which are useful for the synthesis of aristocularine alkaloids. .
