A SELECTIVE BASE-INDUCED REARRANGEMENT OF PERHYDRONAPHTHALANES TO 1,5-CIS-FUSED 10-METHYLENE PERHYDROAZULENES
Wijnberg, Joannes B. P. A.,Groot, Ae. de
, p. 3007 - 3010 (1987)
The rearrangement of perhydronaphthalenic tosylate 3 to 1,5-cis 10-methylene perhydroazulene 4 was achived selectively and in high yield via intramolecular assistance of a 4β hydroxylate.
