โฆ Synopsis
The stereoselective synthesis of a protected 4-fonnyltrinem 8 was accomplished in good yield. This connpound is a I~tenlial intermediate in the synthesis of a wide range of 4-alkyl and alkenyl substituted trineua antibiotics, as evidenced by its reaction with a series of phosphoranes and phosphonatcs.
