Pseudomonas carvotanacetone

A Pseudomonas strain hydroxylates p-menthane to cis-p-menthan-l-ol,84 and microbiological reduction of carvotanacetone with Pseudomonas ovalis gives similar results85 to those obtained with carvone (Vol. 5, p. 24, incorrectly reports inversion at C-4). (—)-Carvotanacetone (30) gives (+)-carvomenthone (31), (—)-... 

Noma, Y., S. Nonomura, and H. Sakai, 1974a. Conversion of (-)-carvotanacetone and (+)-carvotanacetone by Pseudomonas ovalis, strain 38 1637-1642. 

Iso- (49c) and (+)-neoisocarvomenthol (49d) were formed from (+)-carvotanacetone (47) via (-)-isocarvomenthone (48b) by Pseudomonas ovalis, strain 6-1, whereas (+)-neocarvomenthol (49a0 and (-)-carvomenthol (49b0 were formed from (-)-carvotanacetone (47 ) via (+)-carvomen-thone (48a ) by the same bacteria of which 48b, 48a, and 49d were the migor products (Noma et al., 1974a) (Figure 14.103).
