M. Bhupathy et al., A CONVERGENT SYNTHESIS OF A NOVEL NON-PEPTIDYL GROWTH-HORMONE SECRETAGOGUE, L-692,429, Tetrahedron letters, 36(52), 1995, pp. 9445-9448
A practical, convergent synthesis of L-692,429 (1) from three key inte
rmediates - the 3-aminobenzlactam 2, the beta-lactam 3 and the bipheny
ltetrazole 4 is described. The mechanism of the coupling reaction in w
hich 3 is used as a beta-aminoacid equivalent is also presented.
