Oxametallocycloalcanes: (VI)∗-Synthese de Stanna-2 Oxa-1 Cyclopentenes-3 par Action du Dibutylstannane sur Divers Alcools de Type Propargylique

Abstract
According to the observation of Laliberte et al. (1) and our previous investigations (2) (3) on the action of dihydroorganotin compounds with allylic alcohols, we have obtained in good yields various unsaturated organotin cyclic ethers (2-stanna,1-oxacyclopent-3-enes) by dehydrocondensation reactions between dibutyltin dihydride and the following acetylenic alcohols : 1-propyne 3-ol, 1-butyne 3-ol, 3-methyl 1-butyne 3-ol, 1-hexyne 3-ol and 3-methyl 1-pentyne 3-ol. The cleavage of Sn-0 bond of these hetero-cycles by some polar reagents leads to the formation of γ functional “cis” ethylenic chloro tin compounds.
