Sebok,Timar,Eszenyi,Patonay
, p. 6318 - 6321 (2007/10/02)
A facile deoxygenation of a systematic series of substituted 2,2-dimethyl-7-hydroxy-4-chromanones via their sulfonate, isourea, and thiocarbamate derivatives is reported. The synthesis of novel 2,2-dimethyl-7-mercapto-4-chromanones has been accomplished b

Vijayalakshmi,Subramanian,Rajendra
, p. 661 - 663 (2007/10/02)
A convenient preparation of hitherto unknown compounds 3a, 4a, 3c, 4b and 4c by Friedel-Crafts reaction of active phenol derivatives and 3,3-dimethylacrylol chloride using anhydrous aluminium iodide as the condensing agent is described.

Apsimon, J. W.,Herman, L. W.,Huber, C.
, p. 2589 - 2596 (2007/10/02)
The synthesis of 2,2-dimethyl-5-hydroxychromene (1d) is described.The synthesis of the analogous 5,7-dihydroxy derivatives, using similar conditions, yields the adduct 9 derived via a Bucherer type reaction.X-ray analysis of 9 demonstrated that a pyrrolid
