Novel 3-triphenylmethoxy-1-alkynes, 3-triphenylmethoxy-1-trans-alkenyl-dialkyl-alanes, and lithium 3-triphenyl-methoxy-1-trans-alkenyl-dialkyl-alanates

摘要

This disclosure describes 3-triphenylmethoxy-1-alkynes, 3-triphenylmethoxy-1-trans-alkenyl-dialkyl-alanes, and lithium 3-triphenylmethoxy-1-trans-alkenyl-dialkyl alanates useful as intermediates for the preparation of certain 11-hydroxy- and 11-deoxy-9-keto(or hydroxy)-prostanoic acid derivatives which possess bronchodilator, hypotensive, and anti-ulcer activity.
