TOTAL SYNTHESIS OF (+)-SPATOL. A STEREOSPECIFIC CONSTRUCTION OF VICINAL DIEPOXIDES FROM 2,3-EPOXY-1,4-DIOLS
Salomon, Robert G.,Basu, Basudeb,Roy, Subhas,Sharma, Ram B.
, p. 4621 - 4625 (1989)
A total synthesis of (+)-spatol (1) was achived which depends upon a novel stereospecific transformation of trans-2,3-epoxy-1,4-diols to generate sensitive allylic vicinal cis-epoxide in 1.
