## Abstract The structures of the main products resulting from photocyclodimerization of the title compound **2** and of other 3โmethylโsubstituted โoxacyclohexโ2โenโ1โonesโ (=dihydropyranones) were determined by Xโray crystallography. In connection, the ^13^CโNMR chemical shifts of the cyclobutane
## Abstract The 6โhydroxyโ2Hโpyranโ3(6H)โones 1aโd are esterified stereoselectively with acetic and formic acid, and with several amino acids and peptide derivatives using the DCC/DMAP method. The direct synthesis of the 6โalkoxy derivatives 3gโk is also studied.
