In the present study, the reaction of \u03b1\u2010aryl\u2010\u03b2\u2010alkyl\u2010substituted acroleins with ethyl vinyl sulfide was developed with the use of bulky chiral supramolecular Br\u00f8nsted acid catalysts, such as tris(pentafluorophenyl)borane\u2010assisted chiral phosphoric acid catalysts. As a result, cis\u2010cycloadducts as optically active 3,4\u2010dihydro\u20102H\u2010pyrans were exclusively obtained in high yields with high enantioselectivities via the favored endo orbital approach. An obtained optically active cis\u2010isomer could be transformed into the corresponding trans\u2010isomer without a loss of enantiopurity by O,S\u2010acetal epimerization. Moreover, transformations to synthetically useful optically active epoxide and \u03b4\u2010valerolactone are also demonstrated.", "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\uff1a2020/07/01", "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/ajoc.201900104", "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: [M.
