The Pd- and Ni-promoted decarbonylation of aminoacid thioesters proceeds smoothly to yield enamides. The synthesis of the (S)-(Z)-AviMeCys subunit of mersacidin, an MRSA-active lantibiotic, via this approach, is described.

A synthesis of (-)-alantrypinone is described. The synthesis features the use of [Me3AlSPh]Li as a promoter of a 4-iminobenzoxazine to 4-quinazolinone rearrangement and as a reagent for the deprotection of an Fmoc-protected amino acid derivative. (C) 1999 Elsevier Science Ltd, All rights reserved.

This paper presents a synthesis of ent-alantrypinone (ent-6), the enantiomer of a natural product produced by the fungus Penicillium thymicola. The synthesis revolves around the Li[Me(3)AlSPh]-promoted isomerization of iminobenzoxazine 33 to quinazolinone 34, an N-acyliminium ion cyclization that converts enamide 9 to bridged indole 35, and rearrangement of 35 to oxindole ent-6.
