English abstract The reaction of some cis-2-decalones with TTN in CH2Cl2 at room temperature was investigated. The ring contraction reactions occurred in good yields, however the regio- and diastereoselectivity were low. The effect of the alkyl groups in the regiochemistry of the reaction depends on their position at the decalone ring system
Portuguese abstract A reação de uma série de cis-2-decalonas com TTN em CH2Cl2 à temperatura ambiente foi investigada. As reações de contração de anel ocorreram com bons rendimentos, porém a regio- e a diastereosseletividade foram baixas. A influência de grupos alquílicos na regioquímica da reação depende da sua posição no anel decalínico
