名称:
Synthesis of a new ketone and alcohol with C2 symmetry; (S,S,S,S) tricyclo[6.3.0.03,7]undecan-2-onela and (S,S,S,S) tricyclo[6.3.0.03,7]undecan-2-ollb
摘要:
Dissolving metal reduction of known enone 5 affords predominantly the racemic form of title ketone (3) whereas catalytic reduction gives the meso isomer 6. Neither ketone 3 nor alcohol 4 could be satisfactorily resolved. Asymmetric synthesis of (-)-3 and (+)-4 (ee = 91%) was effected from ketone (+)-13.
