The complementary chiral/achiral strands form an excess\u2010handed double\u2010helical structure as supported by intense split\u2010type Cotton effects in the absorption regions of the conjugated backbones biased by the chiral amidinium\u2013carboxylate salt bridges. The double\u2010helical trimer was found to catalyze the direct aldol reaction of cyclohexanone with 4\u2010nitrobenzaldehyde and produce the products with a moderate enantioselectivity despite the fact that the catalytically active bifunctional piperazine/carboxylic acid pair introduced in the middle is achiral, indicating the key role of the one\u2010handed double\u2010helical framework for supramolecular bifunctional organocatalysis.", "subitem_description_type": "Abstract"}]}, "item_10_description_5": {"attribute_name": "\u5185\u5bb9\u8a18\u8ff0", "attribute_value_mlt": [{"subitem_description": "\u30d5\u30a1\u30a4\u30eb\u516c\u958b\uff1a2021-03-01", "subitem_description_type": "Other"}]}, "item_10_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "Wiley"}]}, "item_10_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.1002/chir.23169", "subitem_relation_type_select": "DOI"}}]}, "item_10_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "\"This is the peer reviewed version of the following article: [Taura, D, Shimomura, K, Ousaka, N, Yashima, E.
