Stereospecific lithiation of N-alpha-methylbenzyl benzamides gives configurationally stable tertiary benzyllithiums which undergo a stereospecific dearomatizing cyclization with >99% retention of stereochemistry. The products are partially saturated isoindolinones which carry a new fully-substituted stereogenic centre. A ten-step sequence converts one of these products to the alpha-methyl analogue of kainic acid. (C) 2003 Elsevier Science Ltd. All rights reserved.
