M. Nyerges et al., An intermolecular 1,3-dipolar cycloaddition approach to the tricyclic coreof martinelline and martinellic acid, TETRAHEDR L, 41(41), 2000, pp. 7951-7954
The tricyclic core of the martinellines has been synthesised stereoselectiv
ely in two steps, using 1,3-dipolar cycloaddition of azomethine ylides as a
key step. (C) 2000 Elsevier Science Ltd. All rights reserved.
