prepared, and the structures of these compounds have been unequivocally established. Bimolecular reduction of these ketones, followed by dehydration, gave either bi-indenyl or trans-indanylideneindene derivatives. The mechanisms of these reactions are discussed.

3-methylindanones has not been disclosed. We present herein a nickel catalyzed C−C bond reconstruction sequence of o-bromophenylcyclobutanones using H2O as hydrogen donor, leading to a series of indanones, which can be further converted into other benzene-fused cyclic compounds.
尽管最近在邻卤素束缚苯基环丁酮与其他伙伴的催化开环/交叉偶联过程方面取得了进展,但尚未公开此类前体对 3-甲基茚满酮的单组分扩环。我们在此提出了一种镍催化的邻溴苯基环丁酮的 C-C 键重建序列,使用 H 2 O 作为氢供体,产生一系列茚满酮,这些茚满酮可以进一步转化为其他苯稠合环状化合物。

A series of 1-indanones were synthesized in good yields via tandem Friedel-Crafts acylation and Nazarov cyclization of arenes and alpha,beta-unsaturated acyl chlorides in the presence of aluminum chloride under microwave irradiation.

has been achieved through the merger of iminium ion catalysis and transition-metal catalysis such that asymmetricinduction derives from a readily accessible, inexpensive chiral nonracemic secondary amine catalyst rather than a chiral nonracemic phosphine as is typical of conventional asymmetric hydroacylation methods.
