✦ Synopsis

A new Triorqanotin hydride, Trineophyltin hydride was prepared and its chemo-and stereoselectivity towards reduction of Porn 6,6-homo-and hetero-dihalopenicillanates was examined. The trineophyltin hydride reveals higher stereoselectivity compared to that by tributyltin hydride at 25'C.

The stereoselective synthesis of all-trans 3-methyl-nona-2,4,6-trienol 2 by reductive elimination of the corresponding 1,6-dibenzoate-2-methyl-2(Z),4(Z)-diene is described. This result shows that reductive elimination can be extended to the formation of all-trans methyl substituted polyenes which ar
